KyPlot - Version 2.0 Beta 11 A data-analysis, graphing and drawing program for scientists and engineers. The data-analysis functions include: numerical filtering, differentiation and integration; matrix operations; numerical solutions of nonlinear or differential equations; optimization for arbitrary formulas; time series analysis; wavelet analysis; and many statistics. The graphs (line, scatter, area, bar, stacked bar, pie, radar, polar, bubble, image, contour and table) support X and/or Y error bars, axis breaks, and curve fittings (nonlinear least squares or maximum likelihood fitting for arbitrary functions, polynomial, B-spline fittings, and smoothing spline, local polynomial and wavelet regressions). It also has drawing tools for making schemes for presentation.
