Hi, I am trying to solve an overdetermined systems of linear equations : (A) m-by-n (X)n = (B)m m > n I am using the 'dgels.f' routine from LAPACK. I am getting strage numbers for a matrix made up by me. I am wondering if anyone has (or point me to) a small matrix, for which the answer is verified. I can then use that matrix to check my code. Ideally n=m-1 for my case. Thanks. Pradipta
