Right now the engine consists of my own matrix and vector classes (QuickMatrix and QuickVector). They're fairly robust and a fairly good balance between performance and features, ie no dynamic rescaling, etc...)
The class Matrix is a much refactored version of what I found when I started hacking on on ktechlab. I've written a function called "validateLU" and it seems to be showing that there ARE errors in the LU factorization algorithm. The current engine does not do any row-permutations because the current system tries to optimize things by not completely redoing a matrix that has only had minor changes, that's one potential source of errors. At this point I think we should move to using Eigen and completely junk my idea of a "libktechmath"... I submitted a patch that will agressively abort the program if the engine doesn't produce a valid LU. This problem must be fixed before this branch of ktechlab moves forward. the bug is that severe! =| If this doesn't work, Ktechlab can't simulate jack. =( -- New president: Here we go again...
