dm_la_dgels Subroutine

public subroutine dm_la_dgels(a, b, trans, info)

LA_GELS computes the minimum-norm least squares solution to one or more real or complex linear systems of the form Ax = b, A^Tx = b or A^H*x = b using a QR or LQ factorization of A. Matrix A is rectangular assumed to be of full rank. The vectors b and corresponding solution vectors x are the columns of matrices denoted B and X, respectively.
