Q & A
What is the difference between PSI-Plot and ProStat ?
PSI-Plot and ProStat share a lot of common parts in data analysis and plotting, but each of them has its own emphases.
For data analysis, PSI-Plot targets more generic mathematical problems such as
an algebraic equation
solver, matrix manipulation, ordinary differential equation (ODE) solver, difference equation solver, and digital
signal processing, while ProStat aims at advanced statistical analysis (click
here to see the comparison of highlighted
features). For plotting, both programs do the same in 2D and 3D Cartesian coordinate systems. But PSI-Plot supports other special coordinate systems as well,
such as polar systems, spherical systems, cylindrical systems,
ternary, and Smith.
Does PSI-Plot (or ProStat)
run under a network ?
Both PSI-Plot and Prostat run under networks. By default, the software we will ship is

will ship the network version to our
