NLREG
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. NLREG includes a programming language similar to C that you use for describing the function to be fitted. ... The programming language includes a large selection of built-in library functions (sin, cos, log, exp, etc. ... ) that makes it easy to describe complicated models. ... Two dimensional line and three dimensional surface plots can be generated.
