InterReg 2014

Mathematical Software for Interpolation and Regression

30-Days Demo - for XP to Windows 10 (32 and 64-bit)


Interpolation and Regression are fundamental and important calculations in mathematics. Mr. Newton and Mr. Gauss were engaged in-depth with numerical solutions for these problems. Today, there are improved algorithms, that can solve such tasks.

InterReg allows you to do such complex calculations just with some point-and-click. So this program is not only for mathematics and engineers. The applications are many and reach from education over science to productive use in your company: in example a meaningful sales forecast can be done in minutes.

Over this, the software offers some other functionality to do curve sketching, integration and statistics as well.

InterReg Features

  • new Loading and saving of projects
  • new Undo/Redo
  • new Recalculate
