Polymath and PolymathPlus
PolymathPlus and Polymath are a set of user-friendly numerical analysis programs. They can solve ordinary differential equations and systems of linear or nonlinear equations and also carry out nonlinear regression. PolymathPlus and Polymath are available at https://polymathplus.org/. The files in dark blue can be used in PolymathPlus or Polymath (click to download the file). Corresponding screencasts are listed in light blue. Hover your mouse over each screencast to read the description.
