Cool, I wish I was better a C, but my fun is limited to Python at the
moment, and my real work (Diesel mech) takes priority over learning C.

I keep finding junk that I had removed in my own personal fork but which are still present in the CVS tree... I found a tarball of what I had been passing around before, it probably needs some tidying up before it gets put in one of the SVN branches... If you need it, ask. -- it has problems with it's engine though because it was a snapshot of the changes I was making while I was rebuilding it. A brief profiling run on the SVN sources (using valgrind) showed that, if I am interpreting this correctly, 23% of the execution time was taken up in the [] methods of matrix and Vector. I'm pretty sure that my own Qmatrix and Qvector classes optimized many of the 8 million calls to those functions out... (and this really was a brief run...) Don't worry about my matrix classes messing up the engine, the results should be identical until you start mucking with the LU decomposition solver... |
