how to use cftool non-interactively in matlab

问题

Is there any way to use cftool non-interactively. For example, given x, y and the fitting function, calling cftool to generate and returned the fitted data without using opening the toolbox GUI. Thanks

回答1:

You can use the fit function that comes with Curve Fitting Toolbox. To find out more, type doc fit. Or you can use cftool interactively, then use Generate Code from the File menu to create a function that uses the fit command to repeat your interactive work programmatically. Use this as a template example.

I don't know, but there's another way.

File/Generate Code

function [fitresult, gof] = Custom_fit(x,y,My_Equation)

% example -->My_Equation = 'a*exp(-b*x)+c*exp(-d*x)' % y=f(x)

[xData, yData] = prepareCurveData( x, y );

% Set up fittype and options.
ft = fittype(My_Equation, 'independent', 'x', 'dependent', 'y' );
opts = fitoptions( 'Method', 'NonlinearLeastSquares' );
opts.Display = 'Off';
opts.StartPoint = [0.0376273842264444 0.821185653244809 0.81656489972889 0.961898080855054];

% Fit model to data.
[fitresult, gof] = fit( xData, yData, ft, opts );

end

code.
