NLREG performs nonlinear regression and curve fitting. NLREG fits a mathematical function whose form you specify to a set of data values. Virtually any type of function can be fitted.
a curve fitting program: Lorentzian, Sine, Exponential and Power series are available models to match your data. A Lorentzian series is recommended for real data especially for multiple peaked data. CurvFit is an ex. of Calculus Programming.
Graphing, curve fitting and calculating software. Graphs Cartesian, polar and parametric functions, graphs of tables, implicit functions and inequalities. Calculus features: regression analysis, derivatives, tangents, normals and more.
FindGraph is comprehensive, feature-rich graph editor, as well as a curve-fitting and digitizing tool for engineers, scientists and graduate students. Discover the model that best describes your data.
