Is it possible to obtain the script file for the fitlm function?

I need the script file for the fitlm, using the polyijk attribute, so that I can create my own modified function. Is that possible or should I necessarily use the one given by the Matlab statistics toolbox.

Answer 1

[Sean de Wolski]

edit fitlm

And since fitlm is just a wrapper around LinearModel.fit:

edit LinearModel.fit

Oh, thanks very much. That answers my question.

It is not entirely clear what you are requesting but if you have fit a linear model using fitlm as follows:

mdl = fitlm(...)

You can access the model function this way:

mdl.Formula.ModelFun

If you want to use an custom polynomial function you can type it out:

y ~ 1 + x1^2 ... so on

If you want to use an arbitrary function i recommend fitnlm :

Thanks for replying, but I was hoping to get the code for the function, not the function syntax.

Can you elaborate? its not very clear what you are asking for. What do you mean by code for the function? If it is code for fitlm, then see what Sean posted. If not please explain.
