Excel add-in with eleven powerful worksheet functions for 1, 2 and 3 variable lookup and interpolation (closest-value, linear, piecewise parabolic or hyperbolic, cubic spline) and polynomial curve fitting. Includes online help and example workbooks.

FindGraph is comprehensive, feature-rich graph editor, as well as a curve fitting and digitizing tool for engineers, scientists and graduate students. Convert plots back to X, Y data from any published report for later processing and manipulations.

Adds data curve fitting, interpolation and data smoothing functions to Excel. Functions include polynomial fits, several types of splines, and local regressions. Filters include moving average, Gaussian smoothing and median filtering.

ndCurveMaster was designed to find optimum equations to describe empirical data using a regression method. ndCurveMaster is the first and only program to find the ideal equation to allows the auto fitting of an unlimited number of input variables.
