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
