# 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

• 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
• Interpolation
• Linear Interpolation
• Cubic Splines
• Akima Splines
• Regression
• Regression of arbitrary functions using:
• LBFGS algorithm (quasi-Newton operation)
• Levenberg-Marquardt algorithm
• Curve Sketching
• Numerical derivations, zero crossings, extreme values, inflection points
• Crossings of two curves
• Tangents
• Integrals
• Integrals between the x-axis and between two curves:
• Romberg algorithm
• Simpson algorithm
• Statistics
• Arithmetic mean value
• Median
• Trend
• Correlation (Pearson and Spearman)
• Function Plotter
• Plotting of arbitrary function therms
• 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
