I use SciMOD, Scientific Modeling. The software is friendly, and has basic methods to solve linear systems and it has some other numerical methods. For non linear equations I have to check it out. Also it includes some FEM analysis to solve PDE's , Linear elastics solid problems, heat transfer and fluids, it could be interesting for other purposes. Some videos can be seen at: http://www.youtube.com/watch?v=zecfY_8YPu8 SciMOD is available at : https://itunes.apple.com/us/app/analysis-center/id418595099?ls=1&mt=12 I hope it be useful.
