Hi all,


I'm trying to run the determinant() function a  10x10 matrix that contains all symbolic values. I've searched through the mailing list to find a solution. I've tried ratmax:true and newdet(), but it is still taking forever. In fact, as of writing now it has been going for over 12 hours and still hasn't finished! Is the determinant doing other stuff besides doing the multiplication and addition? Is it trying to simplify/factorise as it goes along?
