To multiply the values in the individual cells by 10 in the above array, you do not need to apply a formula to each individual cell or value. Instead you just need to use a single array formula. Select a range of 3 x 3 cells on another part of the spreadsheet, enter the formula =10*A1:C3 and confirm this entry using the key combination + Shift + Enter. The result is a 3 x 3 array in which the individual values in the cell range (A1:C3) are multiplied by a factor of 10.

Implicit intersection of array formulas

You can also create a "normal" formula in which the reference range, such as parameters, indicate an array formula. This formula is also known as "implicit intersection" of array formula. The result is obtained from the intersection of the reference range and the rows or columns in which the formula is found. If there is no intersection or if the range at the intersection covers several rows or columns, a #VALUE! error message appears. The following example illustrates this concept:

In the table above, place the array formula in D1:

{=A1:A3 + 100}

Cells D1, D2, D3 have values 107, 195, 105 respectively.

Insert the formula below in E2, do not enter as array formula.

=A1:A3 + 100

Cells E1 and E3 are empty, Cell E2 has value 195. This is the implicit intersection of array formulas.

Insert formula below in E4, as in E2.

=A1:A3 + 100

Cell E4 display #VALUE!. Row 4 is out of the range A1:A3 of the formula.

If you enter the array formula directly into the cell, you must use the key combination Shift + + Enter instead of the Enter key. Only then does the formula become an array formula.

The cells in a results array are automatically protected against changes. However, you can edit, delete or copy the array formula by selecting the entire array cell range.

Calc supports inline matrix/array constants in formulas. An inline array is surrounded by curly braces '{' and '}'. Elements can be each a number (including negatives), a logical constant (TRUE, FALSE), or a literal string. Non-constant expressions are not allowed. Arrays can be entered with one or more rows, and one or more columns. All rows must consist of the same number of elements, all columns must consist of the same number of elements.

FREQUENCY

Indicates the frequency distribution in a one-column-array. The function counts the number of values in the Data array that are within the values given by the Classes array.

GROWTH

Diru giddo wolqate rosichi bixxiluwa shallaganno.

Syntax

GROWTH(DataY [; [ DataX ] [; [ NewDataX ] [; FunctionType ] ] ])

DaataY Y daati dira riqiwanno.

DaataX (doorsha) X daati dira riqiwanno.

harooDaataX (doorsha) hornyuwa wirro higge shallagantannoha X daati dira riqiwanno.

FunctionType (optional). If FunctionType = 0, functions in the form y = m^x will be calculated. Otherwise, y = b*m^x functions will be calculated.

In the LibreOffice Calc functions, parameters marked as "optional" can be left out only when no parameter follows. For example, in a function with four parameters, where the last two parameters are marked as "optional", you can leave out parameter 4 or parameters 3 and 4, but you cannot leave out parameter 3 alone.

More explanations on top of this page.

Example

This function returns an array and is handled in the same way as the other array functions. Select a range where you want the answers to appear and select the function. Select DataY. Enter any other parameters, mark Array and click OK.

LINEST

Suwashshu xuruurira danchu garinnidaatu qinoo xaadannoha shaete isitasitikise qolanno.

Syntax

LINEST(data_Y [; data_X [; linearType [; stats]]])

If linearType is FALSE the straight line found is forced to pass through the origin (the constant a is zero; y = bx). If omitted, linearType defaults to TRUE (the line is not forced through the origin).

If stats is omitted or FALSE only the top line of the statistics table is returned. If TRUE the entire table is returned.

LINEST returns a table (array) of statistics as below and must be entered as an array formula (for example by using + Shift + Return rather than just Return).

In the LibreOffice Calc functions, parameters marked as "optional" can be left out only when no parameter follows. For example, in a function with four parameters, where the last two parameters are marked as "optional", you can leave out parameter 4 or parameters 3 and 4, but you cannot leave out parameter 3 alone.

LinearType (optional). If LinearType = 0, then lines will be calculated through the zero point. Otherwise, offset lines will also be calculated. The default is LinearType <> 0.

In the LibreOffice Calc functions, parameters marked as "optional" can be left out only when no parameter follows. For example, in a function with four parameters, where the last two parameters are marked as "optional", you can leave out parameter 4 or parameters 3 and 4, but you cannot leave out parameter 3 alone.

Example

Select a spreadsheet range in which the trend data will appear. Select the function. Enter the output data or select it with the mouse. Mark the Array field, click OK. The trend data calculated from the output data is displayed.
