I have finished copying the non-linear regression code to C. I am attaching a file with my suggested additions to regression.h and regression.c for Gnumeric version 1.1.x Current state: * There should be no problems with the algirithm as I already tested it in Python. * Although I tried to write good code, there are probably problems with the C implementation. * This code is not tested. Where I need help: * I am not very experienced in C, and that probably shows. My work would beneift much from peer review. * I am not sure of how I can test this. Some pointers would help. Cheers, Daniel.
