Solving a linear system with Lapack's dgeqrf_

Question

I am trying to factorize a matrix with the QR factorization in C++, using Lapack\'s functions in order to solve a system of linear equations (Ax=b)

As far as I unde

Answer 1

While this is an old question, but if you are looking for a way to solve LLS using QR with LAPACK use dgels, it does the same as the answer above.
