I am looking for source code for functions which do matrix arithmetic. Specifically, functions such as matrix inversion, reduction, multiplication and computing the determinant of a matrix. I am specifically looking for a Turbo Pascal implementation of these, but source code in any version of Pascal of any other high level language would be greatly appreciated. Any pointers or suggestions are most welcome. Please reply to the poster of this articles is you have any information. Richard S. Penner AT&T Bell Laboratories 708-713-4339

I'm sorry I can't provide a good reference for Matrix functions but I would hate to see one spend endless hours trying to get Press's codes to work (as I have). Maybe it's just deconvolution they're confused about but when I finally figured out that the variable K that they were talking about in the book wasn't the same variable K in the program they supplied I got pretty irritated. I tried to sort it all out but finally wrote my own deconvolver in less time than I had already spent mucking about with their stuff. Mark
