I would like to figure out how to make an cell or structure of cfit objects.

For simple visualization of what I'm trying to do:

for i=1:10
Fits(i)=fit(Xdata,Ydata(i),fittype)
end

My question is similar to: http://www.mathworks.com/matlabcentral/newsreader/view_thread/281759

However, in the above accepted answer, it was suggested to fill up a cell element with the cfit object. I keep getting the following error: "Conversion to cell from cfit is not possible" When trying something similar, such as:

Fits=cell(1,10)
  for i=1:10
  Fits(i)=fit(Xdata,Ydata(i),fittype)
  end

Your suggestions are appreciated!

Try to replace

Fits(i)=fit(Xdata,Ydata(i),fittype)

by

Fits{i} = fit(Xdata,Ydata(i),fittype);

and see Access Data in a Cell Array

isakson ~ I cellute you!

Tisk tisk on me, I should have figured this one out. Obviously, haven't worked much with cells before. Thanks for the documentation link as well.

To Convert the fitted line to a -friendly- array :

fitted_Line_Array = feval( cfitobj , 0:length(data)-1 )

plot(fitted_Line_Array)

feval is used to evaluate a value on the fitted curve. we will use entire xaxis to create it ( like a plot )

Idk if there's a special function to do it faster than this. but I couldn't fint this answer in Matlab Answers so I put it here if someone was looking for it.
