4cfit

Purpose Create a cfit object

Syntax fmodel = cfit(ftype,coef1,coef2,...)

Arguments

Description

fmodel = cfit(ftype,coef1,coef2,...) creates the cfit object fmodel based

on the custom or library model specified by

ftype, and with the coefficients

specified by

coef1, coef2, and so on. You create ftype with the fittype

function.

Remarks cfit is called by the fit function. You should call cfit directly if you want to

assign coefficients and problem parameters to a model without performing a

fit.

Example Create a fit type object and assign values to the coefficients and to the problem

parameter.

m = fittype('a*x^2+b*exp(n*x)','prob','n');

f = cfit(m,pi,10.3,3);
