Curve and Surface Fitting

The automated translation of this page is provided by a general purpose third party translator tool. Or use the utility BixHex to create curvfit. The toolbox lets you perform exploratory data analysis, preprocess and post-process data, compare candidate models, and remove outliers.

Based on your location, we recommend that you select: Working with Curve Fitting Toolbox Fit curves and surfaces to data, including linear and nonlinear regression, splines and interpolation, and smoothing.

Save the extracted files in the directory of your choice.

Curve Fitting Toolbox - MATLAB

There citting many time-saving options such as a copy-and-paste-operation feature which allows you to "paste" a just-completed fitting operation to another curve or data column. Explore the latest features for this product. In your command window not the Matlab windowcd to the directory where you saved the file, and enter the command tar xvfp curvfit. With just a few clicks, you can perform curve fitting and fifting "best-fit" parameter values. You can also add your own function.

Fittig toolbox also supports nonparametric modeling techniques, such as splines, interpolation, and smoothing. Need to fine-tune your curve-fitting analysis? The function showfit simply calls the function ezfit for the active curve and displays the result. After creating a fit, you can apply a variety of post-processing methods for plotting, interpolation, and extrapolation; estimating confidence intervals; and calculating integrals and derivatives.

Matlab often requires more than one ". All Examples Functions Apps More.

There are three ways to perform curve fitting with Matlab: Options for spline fitting in Curve Fitting Toolbox, including Curve Fitting app, using the fit function, or using specialized spline functions.

The key function of the toolbox is ezfitwhich computes the coefficients that fit the data.
