Recursive call: determinant of matrices (greater than 2x2 matrices)

[MarleyMnd]

>>> DETERMINANT

The program I did already can compute the determinant of 2x2 matrices. Thus it can also already compute the inverse matrix of 2x2 matrices.

I don't know how to build the recursive function to compute the determinant of square matrices (greater than 2x2 matrices) in C.
The goal is to compute the inverse of any matrix.

thx.
