Performs multivariate polynomial regression using the Least Squares method. The program determines the coefficients of the polynomial, the generalized correlation coefficient and the standard error of estimate.
Visualizes and studies functions of one variable to find roots, extrema, integral, derivatives, graph. Results can be saved or printed. You can copy the graph to the clipboard. You ...
Finds the relative maxima and minima of functions of several variables in a given interval. You control the maximum error in the computations. Intervals may be explored in search o ...

Approximates tabulated functions in 1 to 4 independent variables by finite power and/or trigonometric series. The program fits the function exactly at the grid points.
Approximates continuous functions in 1 to 4 independent variables by finite power and/or trigonometric series. The program fits the function exactly at the grid points.
