802.0. "matrix solver wanted" by HYDRA::BLATT (Rob Blatt LTN1-1/D07 226-6203) Sun Dec 13 1987 09:01

Does anyone have a program that soves simultaneous equations.  I would like
to solve something with 26 unknowns.  I have over 50 equations.

	There is a matrix package, posted earlier in this conference that is probably still available thru the toolshed. However, you're implying that you have an over determined system and want a best fit somehow. Is this correct? I have a number of routines that may be useful, but have to know which ones you'd need; for example if there is any special structure to your equations (such as circulant, Toeplitz, banded, etc.) there are faster and potentially more accurate methods than a simple solver. - Jim
