I want to use the 'fit' command to model a dataset with a two term Gaussian model. I found an example about how to center and scale polyfit: [p,S,mu] = polyfit(x,y,n) but i have not been able to find an example how to center and scale the 'fit' command and then use the feval command to see the fit y values. Does anyone know how to do it?
MATLAB: Center and scale a fit
fit

If you have Curve Fitting Toolbox, you can use that to do an exponential fitting directly
If not, you can take logarithm of both sides and translate that into a linear fitting problem, i.e.
log(y) = log(a)+b*log(x)
and then use polyfit
Maybe this is what you're looking for,
>> A=rgb2gray(imread('wagon.jpg')); imshow(A);>> [m,n]=size(A);>> drawcircle('Center',[n,m]/2+0.5,'Radius',length(A)/4)
