Curve Fitting and Polynomial Interpolation - This program performs curve fitting / interpolation by using polynomial approximation, in the least squares sense, for any discrete function. Polynomial degree can range between 1 and 9
The special Chebyshev orthogonal polynomials for discrete intervals are used (ref: Abramowitz and Stegun, Handbook of Mathematical Functions, National Bureau of Standards, 1970).
This is a freeware addin for all RPN CalcSeries Advanced Mathematics Calculator registered users.
· • polynomial interpolation
· • automatic and manual modes
· • up to 30 values can be used to define any discrete function
· • results can be displayed in graphs or tables
· • up to 10 different scenarios can be used to represent set of data
· • statistics analysis - the program calculates the minimum, maximum and mean values for the difference between the calculated polynomial approximation and the respective discrete functional value. This way you can check improvements when increasing the polynomial degree.
· • on-line User Guide with examples
· • Hi-Resolution (320x480) support
· • User-friendly interface
· • RPN stack display
· • independent storage registers
· • Upgrades / updates are life-time free of charge
· • Palm keyboard support
· • 5-way-navigation-buttons support
