Function: inv
Description: inv computes the inversematrix. As usally this functionality extends to higher dimensional arrays.


Usage: z = inv (x)
Input:
x array of square matrices
Output:
z array of square matrices

Note:

Example:



x = #(1,2)~#(3,4)

inv (x)

y = #(1,2)~#(2,4)

inv (y)

Result:



Contents of invers

[1,]    -2   1.5 

[2,]     1  -0.5
