A function added by the ShowOff NVSE Plugin version 1.40.

Description
Returns true if an array can be considered a mathematical Matrix, false otherwise.
Expects that either all elements in the main array are sub-arrays (for two-dimensional arrays) containing numbers, or are numbers. The array must have the same number of elements in each row. Empty or invalid arrays are not considered valid matrices.
Two-dimensional and one-dimensional arrays can both be matrices if they follow the above rules.
Syntax
(isMatrix:bool) Matrix_IsMatrix array:array_var
Or:
(isMatrix:bool) Mat_IsMat array:array_var
Example
array_var aRes
aRes = ar_List "test" print "Is array a matrix?: " + $(Matrix_IsMatrix aRes)
Prints that the array is not a valid matrix, since it has a non-numeric member.
aRes = ar_List (Ar_List 1) print "Is array a matrix?: " + $(Matrix_IsMatrix aRes)
Prints that the array is a valid matrix.
aRes = ar_List (Ar_List 1), (Ar_List 2 3) print "Is array a matrix?: " + $(Matrix_IsMatrix aRes)
Prints that the array is not a valid matrix, since its second row has more elements than its first row.
aRes = ar_List (Ar_List 1), (Ar_List 2 SunnyREF) print "Is array a matrix?: " + $(Matrix_IsMatrix aRes)
Prints that the array is not a valid matrix, since its second row has more elements than its first row. Not only that, but one of its elements is also non-numeric.
aRes = ar_List (Ar_List SunnyREF) (Ar_List SunnyREF) print "Is array a matrix?: " + $(Mat_IsMat aRes)
Prints that the array is not a valid matrix, since it has non-numeric elements.
aRes = ar_List (Ar_List 1, 2), (Ar_List 2, 3) print "Is array a matrix?: " + $(Mat_IsMat aRes)
Prints that the array is a valid matrix.
aRes = ar_List 5, (Ar_List 2, 3) print "Is array a matrix?: " + $(Mat_IsMat aRes)
Prints that the array is not a valid matrix, since its second element is an array (expects that either all elements in the main array are sub-arrays, or are numbers).
