Adrian, The third execution of your code gave me the following result. I used Raul's definitions and left out your io, ifio, and ofio and all seemed good.
My questions are, how would you characterize your app (for example, artificial neural network, genetic algorithm) and what are you modeling? Thanks, jbd 1 cycle@show ^:40 (; ; ,:)~ 0 0 ++++ -+++ -+-+ --++ +-+- -+-+ --++ ++-- +-++ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ ---+ +------------+-----------------+ |+-----+----+|0.619296 1.32128| ||_1 _1|_1 1||_1.17174 _1.22751| |+-----+----+| | +------------+-----------------+ -- (B=) ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
