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.

Features:
• Loading and saving of projects
• Undo/Redo
• Recalculate
• Calculates with arbitrary precision.
• Easy graphical usage and state-of-the-art algorithms
– Without a complicated scripting language you are able to do some complex calculations with simple point-and-click.
– So this software targets both mathematicians and non-mathematicians
– Modern algorithms give exact results
– Comprehensive import functions import sampling points from many different formats and databases
