Hello everyone, I'm computing the inverse of a big matrix, 500 x 500. Well, maybe not that big, but I'm getting the error message "General::luc: Result for `1` of badly conditioned matrix `2` may contain significant numerical errors. >>" and I'm wondering if anyone can suggest a workaround. All I can say is that the determinant is very small (-4.327475016428501*10^-1947), and that I can compute the inverse of various submatrices of size 100 x100. Regards, Gregory
