I haven't had a very autodidactic attitude lately and probably never will but I'd still like to learn some TI-Basic. I've visited TI-Basic Developer loads of times already but never managed enough time to actually learn something. I'll keep trying. In the meantime though, I'd like to ask you if you could provide me a code, 68k Basic preferably, for Gauss elimination, or even iterative methods like Jacobi and Gauss-Siedel? Thank you.

Gaussian elimination... well, there's the version without pivoting, and if you do use pivoting (highly recommended, BTW), you can always adapt the pseudocode in Golub/Van Loan

As for the iterative methods... what for? They really are only useful for large and sparse matrices, so unless you expect to be handling matrices much larger than 5050, I see no point in implementing them...

Well I don't really want to use any of this for anything other than to learn from. Thank you for the algorithm.
