Is it possible to integrate a cfit function

I have two data sets 'ymm' and 'v'. I need to integrate the function 'f' found using

        f=fit(ymm,v,'poly8')

The integral is q= Pi (integral to limits of ymm) f^2 dymm

See Integrate cfit object

[Steven Lord]

That allows you to integrate the fit object, but it doesn't allow you to integrate something like the fit squared. To do that, write a function that evaluates the fit and manipulates the result and pass that function into integral. In this case, where the fit is stored in f, use:

integral(@(x) f(x).^2, ...
