transform cfit (fitted data) into a numeric data array

f=fit(x,y,'linearinterp');

I need to save f fitted numeric data from the original data into a different array such as;

fitted_data=f

How I can transform cfit type of fitted data to the numeric (double) fitted data?

If I understand your question, it looks like you want to get the fitted data as an array of doubles.

According to this documentation:

https://www.mathworks.com/help/curvefit/evaluate-a-curve-fit.html

You can supply the fit with a range of values that you are looking for like so:

xi = (2000:10:2050).';

fitted_data = f(xi)

Hope this helps.
