[Gretl-devel] more specific error matrix for eigen()?

Hi, in lib/src/gretl_matrix.c inside the real_gretl_dgeev function on line 9797 I'm seeing:  if (gretl_is_null_matrix(A) || A->rows != A->cols) {         *err = E_INVARG;         return NULL; leading to the user-level generic error message "invalid argument" for example for non-square matrix input into the eigen() function. Do we have some error other than E_INVARG that we could use here to yield something a little more informative? thanks sven
