MDETERM.
public
static determinant(mixed $matrixValues) : float|string
Returns the matrix determinant of an array.
Excel Function: MDETERM(array)
Parameters
- $matrixValues : mixed
-
A matrix of values
Return values
float|string —The result, or a string containing an error
identity()
MUnit.
public
static identity(mixed $dimension) : array<string|int, mixed>|string
Parameters
- $dimension : mixed
-
Number of rows and columns
Return values
array<string|int, mixed>|string —The result, or a string containing an error
inverse()
MINVERSE.
public
static inverse(mixed $matrixValues) : array<string|int, mixed>|string
Returns the inverse matrix for the matrix stored in an array.
Excel Function: MINVERSE(array)
Parameters
- $matrixValues : mixed
-
A matrix of values

sequence()
SEQUENCE.
public
static sequence([mixed $rows = 1 ][, mixed $columns = 1 ][, mixed $start = 1 ][, mixed $step = 1 ]) : array<string|int, mixed>|string
Generates a list of sequential numbers in an array.
Excel Function: SEQUENCE(rows,[columns],[start],[step])
Parameters
- $rows : mixed = 1
-
the number of rows to return, defaults to 1
