mathworks刚刚推出的工具箱,事实上大家在使用matlab6.1的时候也注意到
curve fit的功能已经添加到菜单中了。

Overview
The Curve Fitting Toolbox provides a central access point for the
functions you need to perform applications that involve curve fitting.
The Toolbox extends the MATLAB environment with integrated tools for:
Previewing and preprocessing data
Creating, comparing, and managing models
Using a variety of standard and custom fitting models
Fitting with standard and robust methods
Analyzing fits
The functionality in the Curve Fitting Toolbox is available through an
intuitive visual interface or at the command line. In addition,
toolbox functions are implemented in the open MATLAB language. This
gives you access to the source code, which allows you to learn from
and customize existing algorithms or develop your own.
Key Features
Interactive point-and-click interface that unifies key aspects of
curve fitting
Preprocessing routines including data scaling, sectioning, smoothing,
and removal of outliers
Extensive library of linear and nonlinear parametric fitting models,
with optimized starting points and solver parameters for nonlinear
models
Varied linear and nonlinear fitting methods including least squares,
weighted least squares, or robust fitting procedures (all with or
without bounds on coefficients)
Custom linear and nonlinear model development
Nonparametric fitting using splines and interpolants
Interpolation, extrapolation, differentiation, and integration of fits
