Hi
Fitting a polynomial in Matlab to some data (x, y) is easy using polyfit as e.g.
p_RvsT = polyfit(r_vs_t(:, 1), r_vs_t(:, 2), 1);
However, say that my y-data has some error assigned to it. I have searched the forum, but I can't find information on how to include the errors in the y-data. I would be very happy to be pointed in the correct direction.
Best, Niles.

How about the additional outputs in regress? Or if you're on R2012a, LinearModel? (Both of these require the Statistics Toolbox)
