cflibhelp - Information on library models

Syntax

cflibhelp cflibhelp libtype

Description

cflibhelp displays the names, equations, and descriptions of all models in the curve-fitting library. Library names are used as input arguments in the fit and fittype functions.

cflibhelp libtype restricts the display of names, equations, and descriptions to the subcategory of library models libtype. Recognized library types are listed in the table below.

`libtype`	Description
`distribution`	Probability distribution models
`exponential`	One-term and two-term exponential models
`fourier`	Fourier polynomial models
`gaussian`	Sums of Gaussian models, up to eight terms
`interpolant`	Interpolating models, including linear, nearest neighbor, cubic spline, and shape-preserving cubic spline
`polynomial`	Polynomial models, up to ninth degree
`power`	One-term and two-term power models
`rational`	Ratios of polynomial models, up to degree 5 in both the numerator and the denominator
`sin`	Sums of sinusoidal models, up to eight terms
`spline`	Cubic spline and smoothing spline models

For more information on library models, refer to the Library Models section of the User's Guide.
