NAME
invert_matrix0 -- Inverse of a matrix, C-convention
PROTOTYPE
float invert_matrix0(int iDim, float* pfA, float* pfInverse)
ARGUMENTS
- int iDim
- dimension
- float* pfA
- matrix
- float* pfInverse
- inverse of matrix
DESCRIPTION:
Find the inverse y[0..n-1][0..n-1] of a matrix a[0..n-1][0..n-1], so that
AY=1=YA. The input matrix 'a' will be destroyed afterwards. The
matrices are given as linear arrays, i.e. A[i][j]=A[i*n+j]
The algorithm employs one step of iterative improvement of each solution.
RETURN VALUE:
The matrix determinant. A return value of zero indicates that the
matrix was singular. The inverse pfInverse is invalid in this case.
