Hi,
I'm having an indexing problem. I have placed a for loop around an nlinfit statement to perform regression for a data matrix. The data matrix is a 16 by 5 matrix, where the fit is over the 16 rows, performed for each column. How can I index properly to output each set of fit parameters, a total of five fits with three parameters each, in a final output matrix. The output matrix would be a 3 by 5 matrix.
Any tips?
Avi

[rows, columns] = size(data);
for col = 1 : columns
% Extract this column only.
thisColumn = data(:, col);
% Do the fitting.
nlfit(..thisColumn..........
end

You're welcome. Can you go ahead and mark it "Accepted" so others will know they don't need to help you any more by opening this and responding?
