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:
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
