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
