Simple question on how to get fitted data matrix from fit function

Good morning,

I am having a rather simple issue but after having googled it and looked for it on Matlab Central, I just can´t find the solution for it ..

I am fitting experimental data with various models using a curve fitting toolbox script with success in the way that I am getting all the curves I need (experimental, fitted and 95%confidence) and the fitted parameters.

I simply would like to get one way or another the data used to plot the fitted curve. There must be a smarter way than reinjecting the coefficients in the equation and generating a new matrix and I can´t find it.

Any ideas?

Thanks !

David

I don't have the curve fitting toolbox, but if you had the design matrix you could multiply the design matrix by the coefficients. I assume you know of

polyval()
