Title: Implementation of minres

minres is a CG-like algorithm for solving system of the form AX=b,
but that can work on singular or ill-conditioned matrices A. In
such cases it returns a least square solution (though not necessary
the pseudoinverse - there is a different algorithm that does that
minres-qlp)
