Yes, but now you can't pretend that this is even a toy model of numerical code. Continuing to machine precision in a solver is, well, ridiculous. I know this is educational code, and the power-based solution is educationally interesting and all, but it doesn't generalize to reality. - Johann ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
