MAXIFS function
Returns the maximum of the values of cells in a range that meets multiple criteria in multiple ranges.
This function is available since LibreOffice 5.2.
MAXIFS(Func_Range; Range1; Criterion[; Range2; Criterion2][; … ; [Range127; Criterion127]])
Func_Range – required argument. A range of cells, a name of a named range or a label of a column or a row containing values for calculating the maximum.
Range1 – required argument. It is a range of cells, a name of a named range, or a label of a column or a row, to which the corresponding criterion is to be applied.
Criterion: A criterion is a single cell Reference, Number or Text. It is used in comparisons with cell contents.
A reference to an empty cell is interpreted as the numeric value 0.
A matching expression can be:

A Number or Logical value. A matching cell content equals the Number or Logical value.

A value beginning with a comparator (<, <=, =, >, >=, <>).
For =, if the value is empty it matches empty cells.
For <>, if the value is empty it matches nonempty cells.
For <>, if the value is not empty it matches any cell content except the value, including empty cells.
Note: "=0" does not match empty cells.
For = and <>, if the value is not empty and can not be interpreted as a Number type or one of its subtypes and the property Search criteria = and <> must apply to whole cells is checked, comparison is against the entire cell contents, if unchecked, comparison is against any subpart of the field that matches the criteria. For = and <>, if the value is not empty and can not be interpreted as a Number type or one of its subtypes applies.

Other Text value. If the property Search criteria = and <> must apply to whole cells is true, the comparison is against the entire cell contents, if false, comparison is against any subpart of the field that matches the criteria. The expression can contain text, numbers, regular expressions or wildcards (if enabled in calculation options).
Range2 – Optional. Range2 and all the following mean the same as Range1.
Criterion2 – Optional. Criterion2 and all the following mean the same as Criterion.
The search supports wildcards or regular expressions. With regular expressions enabled, you can enter "all.*", for example to find the first location of "all" followed by any characters. If you want to search for a text that is also a regular expression, you must either precede every character with a "\" character, or enclose the text into \Q...\E. You can switch the automatic evaluation of wildcards or regular expression on and off in .
When using functions where one or more arguments are search criteria strings that represents a regular expression, the first attempt is to convert the string criteria to numbers. For example, ".0" will convert to 0.0 and so on. If successful, the match will not be a regular expression match but a numeric match. However, when switching to a locale where the decimal separator is not the dot makes the regular expression conversion work. To force the evaluation of the regular expression instead of a numeric expression, use some expression that can not be misread as numeric, such as ".[0]" or ".\0" or "(?i).0".
Func_Range and Range1, Range2... must have the same size, otherwise the function returns err:502  Invalid argument.
The logical relation between criteria can be defined as logical AND (conjunction). In other words, if and only if all given criteria are met, a value from the corresponding cell of the given Func_Range is taken into calculation.
The function can have up to 255 arguments, meaning that you can specify 127 criteria ranges and criteria for them.
If a cell contains TRUE, it is treated as 1, if a cell contains FALSE – as 0 (zero).
This function is part of the Open Document Format for Office Applications (OpenDocument) standard Version 1.2. (ISO/IEC 26300:22015)

In all examples below, ranges for calculation contain the row #6, which is ignored because it contains text.
Simple usage
=MAXIFS(B2:B6;B2:B6;"<35")
Calculates the maximum of values of the range B2:B6 that are greater than or equal to 20. Returns 35. The fifth row does not meet the criterion.
=MAXIFS(C2:C6;B2:B6;">=20";C2:C6;"<90")
Calculates the maximum of values of the range C2:C6 that are lower than 90 and correspond to cells of the B2:B6 range with values greater than or equal to 20. Returns 85, because the fourth and fifth rows do not meet at least one criterion.
Using regular expressions and nested functions
=MAXIFS(C2:C6;B2:B6;">"&MIN(B2:B6);B2:B6;"<"&MAX(B2:B6))
Calculates the maximum of values of the range C2:C6 that correspond to all values of the range B2:B6 except its minimum and maximum. Returns 190, because only the fourth row meet the criteria.
=MAXIFS(C2:C6;A2:A6;"pen.*";B2:B6;"<="&MAX(B2:B6))
Calculates the maximum of values of the range C2:C6 that correspond to all cells of the A2:A6 range starting with "pen" and to all cells of the B2:B6 range except its maximum. Returns 85, because only the third row meets all criteria.
Reference to a cell as a criterion
If you need to change a criterion easily, you may want to specify it in a separate cell and use a reference to this cell in the condition of the MAXIFS function. For example, the above function can be rewritten as follows:
=MAXIFS(C2:C6;A2:A6;E2&".*";B2:B6;"<"&MAX(B2:B6))
If E2 = "pen", the function returns 65, because the reference to the cell is substituted with its content.
