Calculate determinant for matrix using MKL

Hi, I need to calculate the determinant of a square matrix with MKL(ipp 9.0 - parallel_studio_xe_2016). I searched solution for whole day but still not find the solution.

Which approach should I follow?

Thank you.

Hi,

Are you interested in determinant of sparse or dense matrix? If dense than mecej4 is correct - dgetrf is the way to find it. For sparse matrix dss routine return determinant value

Thanks,

Alex
