MoorePenrose pseudoinverse in MKL

[bb_12_bb_12]

Is using (?)DGESVD the only way to calculate pseudoinverse for a general (not square) matrix in MKL? Is there a single function that will take let's say a 5x2 matrix and calculate a pseudoinverse?

dgelss can do the job with one input your matrix, the other the unit matrix
