MATLAB: Section can’t find private function

Question

I've got a script that has been broken down into sections and which uses functions which I've put in a private/ folder. When running the entire script it can find the functions without problem, but when I run a single section, it gives me the error:

Undefined function 'createFit' for input arguments of type 'struct'.

Is this because MATLAB runs scripts and section differently?

Answer 1

Hi Jean-Paul,

Your observation is correct. To evaluate a section, the script must contain all the values it requires, or the values must exist in the MATLAB workspace. To learn more about evaluating code sections, you can visit the documentation page here: https://www.mathworks.com/help/matlab/matlab_prog/run-sections-of-programs.html

I hope this helps.
