WARNING: DO NOT USE MAZTRIX FOR MISSION CRITICAL CALCULATIONS!!!
Maztrix is a small program (and library) that can be used for elementary matrix operations. Maztrix can row reduce, find determinants, output to TeX, as well as do many other useful things. Maztrix is still in the early stages of development and should not be used for mission critical calculations.
