Dear all
I have the next code which I found in curve fitting in matlab. The code displays the m and c from a file in workspace called ans and sse in file called gof . I do not know how to open this files. please is there any method to save m,c and sse in matrix.
You can run the next code to see the solution and files in work space.
function [fitresult, gof] = createFit(x, y)
%CREATEFIT(X,Y)
% Create a fit.
%
% Data for 'examle 13.2' fit:
% X Input : x
% Y Output: y
% Output:
% fitresult : a fit object representing the fit.
% gof : structure with goodness-of fit info.
%
% See also FIT, CFIT, SFIT.

%%Fit: 'examle 13.2'.

[xData, yData] = prepareCurveData( x, y );
% Set up fittype and options.
ft = fittype( '((.9)^(1-m/2)+(1-m/2)*c*(pi)^(m/2)*x)^(2/(2-m))', 'independent', 'x', 'dependent', 'y' );
opts = fitoptions( ft );

% Fit model to data.

% Plot fit with data.

legend( h, 'y vs. x', 'examle 13.2', 'Location', 'NorthEast' );
% Label axes

I appreciate you help.

coeffnames(fitresult)
coeffvalues(fitresult)
gof will not be a file: it will be a structure.
gof.sse
will show you the sse.
