My dim recollection is that I triangularized Matrix M, giving Matrix T, and then the inverse is easy to compute. From that I went backwards and got the inverse. I've just finished looking in my files on Matrix problems, but was unable to find anything; very vexing. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
