ZGELS Example

The routine solves overdetermined or underdetermined complex linear systems involving a rectangular matrix A, or its transpose, using a QR or LQ factorization of A. The routine assumes that A has full rank.

Several right-hand side vectors b and solution vectors x can be handled in a single call; they are stored as the columns of the right-hand side matrix B and the solution matrix X.
