[Matlisp-users] least-squares estimate

[Evan M. <eva...@gm...>]

Hi,

I found the need to find the least-squares solution of a classical
equation Ax = b, so I added a binding for the lapack function DGELSY.

This is the one that solves rectangular real linear least squares
problems using a complete orthogonal factorization (see [1] and [2]).

Please find a patch attached.

I authorize you to incorporate it to matlisp as is or after
modification, using the same license as other parts of matlisp.

Cheers,

Evan
