MATLAB: How to run a curve approximation on a script using a function defined in a file and display the goodness of fit in a command window

Question

I want to do a curve approximation on a script and show the goodness of fit in the command window at the same time as the result. （ SSE. Determination Factor, Degree of Freedom Adjusted Determination Factor, RMSE, etc.).

What syntax do I need to put in my script to make it appear in a command window or workspace?

Answer 1

You can't use the curve fit tool for a curve defined in an mfile. You can use lsqcurvefit, if you have the optimization toolbox, but you will have to do your own calculation of the goodness of fit metrics.
