Publisher's description

From Eastern Star Software :

Power-Surface offers linear, quadratic, and higher-power least-square curve/surface fitting for the given column-wise numeric data. To perform the fitting, the aforesaid algebraic power series function is assumed, and then the sum of the squares of deviations from the assumed function-value is minimized, thereby generating a set of linear simultaneous equations. This set is then auto-solved by standard Gaussian-elimination method, giving the fitting parameters (new users should refer to the tutorials).

To avoid calculation errors, constant factors and decimal-points in the given data are first shifted, but finally re-corrected. The Saw-File subroutine allows vertical copying/pasting of numeric data columns from text files. Version 1.5 provides point-by-point comparison for the accepted and the fitted (i.e., recalculated) values of the dependent variable, as a further measure of accuracy for the fitting performed.

What's new in this version:

Version 1.5 provides point-by-point comparison for the accepted and the fitted (i.e., recalculated) values of the dependent variable, as a further measure of accuracy for the fitting performed.
