Axuda do LibreOffice 25.8
Provee unha colección de métodos para manipular e transformar formacións de unha dimensión (vectores) e de dúas (matrices). A colección inclúe operacións de conxunto, ordenación, importación e exportación a partir de arquivos de texto.
As matrices con máis de dúas dimensións non poden utilizarse cos métodos deste servizo, sendo a única excepción o método CountDims, que acepta matrices con calquera número de dimensións.
Os elementos de matrices poden conter calquera tipo de valor, incluindo(sub)matrices.
Antes de poder utilizar o servizo Matriz, débese cargar a biblioteca ScriptForge mediante:
GlobalScope.BasicLibraries.loadLibrary("ScriptForge")
A carga da biblioteca creará o obxecto SF_Array, que pode utilizarse para chamar aos métodos do servizo Matriz.
Os seguintes fragmentos de código mostran as diversas formas de chamar aos métodos no servizo Matriz (o método Append úsase como exemplo):
Dim arr : arr = Array(1, 2, 3)
arr = SF_Array.Append(arr, 4)
Dim arr : arr = Array(1, 2, 3)
Dim svc : svc = SF_Array
arr = svc.Append(arr, 4)
Dim arr : arr = Array(1, 2, 3)
Dim svc : svc = CreateScriptService("Array")
arr = svc.Append(arr, 4)
Debido a que Python integra a compatibilidade para listas e tuplas, a maioría dos métodos no servizo Matriz só están dispoñíbeis para secuencias BASIC. A única excepción é ImportFromCSVFile, que se admite tanto en BASIC como en Python.
O primeiro argumento da maioría de métodos é o obxecto matricial para considerar. Sempre se pasa por referencia e se deixa sen cambios. Métodos como Append, Prepend, etc. devolven un novo obxecto matricial despois da súa execución.
Agrega os elementos enumerados como argumentos ao final da matriz de entrada.
svc.Append(array_1d: any[0..*], arg0: any, [arg1: any] ...): any[0..*]
array_1d: A matriz preexistente pode estar baleira.
arg0, arg1, ...: elementos que serán engadidos a array_1d
Dim a As Variant
a = SF_Array.Append(Array(1, 2, 3), 4, 5)
' (1, 2, 3, 4, 5)
Agrega unha nova columna á dereita dunha matriz bidimensional. A matriz resultante ten os mesmos límites inferiores que a matriz bidimensional incial.
svc.AppendColumn(array_2d: any[0..*, 0..*], column: any[0..*]): any[0..*, 0..*]
array_2d: a matriz preexistente pode estar baleira. Se esta matriz só ten unha dimensión, considérase como a primeira columna da matriz bidimensional resultante.
columna: Unha matriz unidimensional con tantos elementos como filas en matriz_2d.
Dim a As Variant, b As variant
a = SF_Array.AppendColumn(Array(1, 2, 3), Array(4, 5, 6))
' ((1, 4), (2, 5), (3, 6))
b = SF_Array.AppendColumn(a, Array(7, 8, 9))
' ((1, 4, 7), (2, 5, 8), (3, 6, 9))
c = SF_Array.AppendColumn(Array(), Array(1, 2, 3))
' ∀ i ∈ {0 ≤ i ≤ 2} : b(0, i) ≡ i
Amecer unha fila nova por debaixo dunha matriz bidimensional. A matriz resultante ten os mesmos límites inferiores que a matriz bidimensional inicial.
svc.AppendRow(array_2d: any[0..*, 0..*], row: any[0..*]): any[0..*, 0..*])
matriz_2d: A matriz preexistente, que pode estar baleira. Se esa matriz ten unha dimensión considérase como primeira fila da matriz bidimensional resultante.
fila: Unha matriz unidimensional con tantos elementos como columnas en matriz_2d.
Dim a As Variant, b As variant
a = SF_Array.AppendRow(Array(1, 2, 3), Array(4, 5, 6))
' ((1, 2, 3), (4, 5, 6))
b = SF_Array..AppendRow(Array(), Array(1, 2, 3))
' ∀ i ∈ {0 ≤ i ≤ 2} : b(i, 0) ≡ i
Comprobe se unha matriz unidimensional contén determinado número, texto ou data. A comparación de texto pode distinguir maiúsculas de minúsculas ou non.
As matrices de entrada ordenadas teñen que ser enchidas homoxeneamente, o que significa que todos os elementos deben ser escalares do mesmo tipo (non se permiten elementos Baleiro e Null).
O resultado do método é impredicíbel se a matriz se anuncia como ordenada cando de feito non o está.
Realízase unha busca binaria cando a matriz está ordenada; caso contrario, simplemente se analiza de arriba a abaixo e se ignoran os elementos Baleiro e Null.
svc.Contains(array_1d: any[0..*], tofind: any, casesensitive: bool = False, sortorder: str = ""): bool
matriz_1d: A matriz que se vai analizar.
paraAtopar: Un número, unha data ou unha cadea que atopar.
maiúsculasMinúsculas: Só para a comparación de cadeas (Por omisión = Falso).
tipoOrdenación: pode ser «ASC», «DESC» ou «» (sen ordenar). O valor por omisión é "".
Dim a As Variant
a = SF_Array.Contains(Array("A","B","c","D"), "C", SortOrder := "ASC") ' True
SF_Array.Contains(Array("A","B","c","D"), "C", CaseSensitive := True) ' False
Almacena o contido dunha matriz bidimensional non obxecto de ScriptForge.Dictionary.
A chave extráese da primeira columna, o elemento da segunda.
svc.ConvertToDictionary(array_2d: any[0..*, 0..1]): obj
matriz_2d: Dato que se converten nun obxecto de ScriptForge.Dictioanry.
A primeira columna debe conter exclusivamente cadeas dunha lonxitude maior que cero, en calquera orde. Estes valores empréganse como etiquetas no dicionario.
A segunda columna contén os datos que se asociarán á etiqueta correspondente do dicionario.
Dim a As Variant, b As Variant
a = SF_Array.AppendColumn(Array("a", "b", "c"), Array(1, 2, 3))
b = SF_Array.ConvertToDictionary(a)
MsgBox b.Item("c") ' 3
Crea unha copia dunha matriz de unha ou dúas dimensións.
svc.Copy(array_nd: any[0..*]): any[0..*]
svc.Copy(array_nd: any[0..*, 0..*]): any[0..*, 0..*]
matriz_nd: A matriz 1D ou 2D que se vai copiar.
Unha asignación simple dun obxecto Matriz copia esta referencia no canto de crear unha copia do contido do obxecto. Vexa o exemplo aquí abaixo:
Dim a as Variant, b as Variant
a = Array(1, 2, 3)
' A asignación de abaixo faise por referencia
b = a
' Logo, cambiar os valores de «b» cambiará tamén «a»
b(0) = 10
MsgBox a(0) ' 10
Ao empregar o método Copiar faise unha copia do obxecto Matriz enteiro. No exemplo de embaixo, a e b son obxectos diferentes e cambiar valores en b non afecta os valores de a.
Dim a as Variant, b as Variant
a = Array(1, 2, 3)
' Crea unha copia de «a» empregando o método «Copiar»
b = SF_Array.Copy(a)
b(0) = 10
MsgBox a(0) ' 1
Conta o número de dimensións dunha matriz. O resultado pode ser maior que 2.
Se o argumento non é unha matriz devolve -1
Se a matriz non está inicializada devolve 0.
svc.CountDims(array_nd: any): int
matriz_nd: A matriz que se examina.
Dim a(1 To 10, -3 To 12, 5)
MsgBox SF_Array.CountDims(a) ' 3
Constrúa un conxunto, como matriz indexada en cero, aplicando a operador de diferenza nas dúas matrices de entrada. Os elementos resultantes orixínanse da primeira matriz e non da segunda
A matriz resultante ordénase de maneira ascendente.
Ambas as dúas matrices de entrada teñen que ser enchidas homoxeneamente, os seus elementos deben ser escalares do mesmo tipo. Os elementos Baleiro e Null están prohibidos.
A comparación de texto pode distinguir maiúsculas de minúsculas ou non.
svc.Difference(array1_1d: any[0..*], array2_1d: any[0..*], casesensitive: bool = False): any[0..*]
matriz1_1d: Unha matriz de referencia unidimensional cuxos elementos se examinan para seren retirados.
matriz2_1d: Unha matriz unidimensional cuxos elementos se substraen da primeira matriz de entrada.
maiúsculasMinúsculas: Este argumento só se aplica se as matrices consisten en cadeas (Por omisión = Falso).
Dim a As Variant
a = SF_Array.Difference(Array("A", "C", "A", "b", "B"), Array("C", "Z", "b"), True)
' ("A", "B")
Escribe todos os elementos da matriz secuencialmente nun ficheiro de texto. Se o ficheiro xa existe, este será substituído sen aviso.

array_2d: A matriz da que extraer.
columnindex: The column number to extract - must be in the interval [LBound, UBound].
'Creates a 3x3 matrix: |1, 2, 3|

Dim mat as Variant, col as Variant
mat = SF_Array.AppendRow(Array(), Array(1, 2, 3))
mat = SF_Array.AppendRow(mat, Array(4, 5, 6))
mat = SF_Array.AppendRow(mat, Array(7, 8, 9))
'Extracts the third column: |3, 6, 9|
col = SF_Array.ExtractColumn(mat, 2)
Extract from a two dimension array a specific row as a new array.

Dim mat as Variant, row as Variant
mat = SF_Array.AppendRow(Array(), Array(1, 2, 3))
mat = SF_Array.AppendRow(mat, Array(4, 5, 6))
mat = SF_Array.AppendRow(mat, Array(7, 8, 9))
'Extracts the first row: |1, 2, 3|
row = SF_Array.ExtractRow(mat, 0)
Stack all single items of an array and all items in its subarrays into one new array without subarrays. Empty subarrays are ignored and subarrays with a number of dimensions greater than one are not flattened.
svc.Flatten(array_1d: any[0..*]): any[0..*]
array_1d: The pre-existing array, may be empty.
Dim a As Variant
a = SF_Array.Flatten(Array(Array(1, 2, 3), 4, 5))
' (1, 2, 3, 4, 5)
You can use the Flatten method along with other methods such as Append or Prepend to concatenate a set of 1D arrays into a single 1D array.
Next is an example of how the methods Flatten and Append can be combined to concatenate three arrays.
'Creates three arrays for this example
Dim a as Variant, b as Variant, c as Variant
a = Array(1, 2, 3)
b = Array(4, 5)
c = Array(6, 7, 8, 9)
'Concatenates the three arrays into a single 1D array
Dim arr as Variant
arr = SF_Array.Flatten(SF_Array.Append(a, b, c))
'(1, 2, 3, 4, 5, 6, 7, 8, 9)
Import the data contained in a comma-separated values (CSV) file. The comma may be replaced by any character.
The applicable CSV format is described in IETF Common Format and MIME Type for CSV Files.
Each line in the file contains a full record (line splitting is not allowed).
However sequences like \n, \t, ... are left unchanged. Use SF_String.Unescape() method to manage them.
The method returns a two dimension array whose rows correspond to a single record read in the file and whose columns correspond to a field of the record. No check is made about the coherence of the field types across columns. A best guess will be made to identify numeric and date types.
If a line contains less or more fields than the first line in the file, an exception will be raised. Empty lines however are simply ignored. If the size of the file exceeds the number of items limit (see inside the code), a warning is raised and the array is truncated.
svc.ImportFromCSVFile(filename: str, delimiter: str = ',', dateformat: str = ''): any[0..*]
filename: The name of the text file containing the data. The name must be expressed according to the current FileNaming property of the SF_FileSystem service.
delimiter: A single character, usually, a comma, a semicolon or a TAB character (Default = ",").
dateformat: A special mechanism handles dates when dateformat is either "YYYY-MM-DD", "DD-MM-YYYY" or "MM-DD-YYYY". The dash (-) may be replaced by a dot (.), a slash (/) or a space. Other date formats will be ignored. Dates defaulting to an empty string "" are considered as normal text.
Consider the CSV file "myFile.csv" with the following contents:
Name,DateOfBirth,Address,City
Anna,2002/03/31,"Rue de l'église, 21",Toulouse
Fred,1998/05/04,"Rue Albert Einstein, 113A",Carcassonne
The examples below in Basic and Python read the contents of the CSV file into an Array object.
Dim arr As Variant
arr = SF_Array.ImportFromCSVFile("C:\Temp\myFile.csv", DateFormat := "YYYY/MM/DD")
MsgBox arr(0, 3) ' City
MsgBox arr(1, 2) ' Rue de l'église, 21
MsgBox arr(1, 3) ' Toulouse
from scriptforge import CreateScriptService
svc = CreateScriptService("Array")
bas = CreateScriptService("Basic")
arr = svc.ImportFromCSVFile(r"C:\Temp\myFile.csv", dateformat = "YYYY/MM/DD")
bas.MsgBox(arr[0][3]) # City
bas.MsgBox(arr[1][2]) # Rue de l'église, 21
bas.MsgBox(arr[1][3]) # Toulouse
Look in a one dimension array for a number, a string or a date. Text comparison can be case-sensitive or not.
If the array is sorted it must be filled homogeneously, which means that all items must be scalars of the same type (Empty and Null items are forbidden).
The result of the method is unpredictable when the array is announced as sorted and actually is not.
A binary search is performed on sorted arrays. Otherwise, arrays are simply scanned from top to bottom and Empty and Null items are ignored.
The method returns LBound(input array) - 1 if the search was not successful.
svc.IndexOf(array_1d: any[0..*], tofind: any, casesensitive: bool = False, sortorder: str = ''): int
array_1d: The array to scan.
tofind: A number, a date or a string to find.
casesensitive: Only for string comparisons (Default = False).
sortorder: It can be either "ASC", "DESC" or "" (not sorted). The default value is "".

a = SF_Array.Insert(Array(1, 2, 3), 2, "a", "b")
' (1, 2, "a", "b", 3)
Inserts into a sorted array a new item on its place.
The array must be filled homogeneously, meaning that all items must be scalars of the same type.

array_1d: The array into which the value will be inserted.
item: The scalar value to insert, of the same type as the existing array items.

Build a set, as a zero-based array, by applying the intersection set operator on the two input arrays. Resulting items are contained in both arrays.
The resulting array is sorted in ascending order.
Both input arrays must be filled homogeneously, in other words all items must be scalars of the same type. Empty and Null items are forbidden.

svc.Join2D(array_2d: any [0..*, 0..*], [columndelimiter: str], [rowdelimiter: str], [quote: str]): str
array_2d: Each item must be either text, a number, a date or a boolean.
Dates are transformed into the YYYY-MM-DD hh:mm:ss format.
Invalid items are replaced by a zero-length string.
