PSIPlot and ProStat share a lot common parts in data analysis and plotting, but each of them has
its own emphases. For data analysis part, PSIPlot is targeting for more generic mathematical problems
such as algebraic equation solver, matrix manipulation, ordinary differiential equation (ODE) solver,
difference equation solver, and digital signal processing; while ProStat aims at advanced statistical
analysis (click here to see the highlighted features). For plotting part,
both programs do the same for 2D and 3D Cartesian coordinate system. But PSIPlot does support other
special coordinate systems as well. Such as polar system, spherical system, cylindrical system, ternary,
and Smith.
