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:
1. Calculates with arbitrary precision.
2. 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
3. Interpolation
* Linear Interpolation
* Cubic Splines
* Akima Splines
4. Regression
* Regression of arbitrary functions using:
* LBFGS algorithm (quasi-Newton operation)
* Levenberg-Marquardt algorithm
5. Curve Sketching
* Numerical derivations, zero crossings, extreme values, inflection points
* Crossings of two curves
* Tangents
6. Integrals
* Integrals between the x-axis and between two curves:
* Romberg algorithm
* Simpson algorithm
7. Statistics
* Arithmetic mean value
* Median
* Trend
* Correlation (Pearson and Spearman)
8. Function Plotter
* Plotting of arbitrary function therms
9. Other Features
* Cartesian coordinate system
* Optional date/time values on the abscissa
* Any number of graphs and value lists
* Printing
* Calculation and export of interpolated sample points

Please Note: this program is free for students and schools only.
