Pretty much what it says. The line choice = eoption; implies that eoption is a function call (because it is asking for an output, to be assigned to choice). But eoption is a script, not a function.
The difference is in how variables are managed. Scripts work with the base MATLAB workspace. Functions use local workspaces, so variables are local. So your options are:
- Turn eoption into a function by adding the line function choice = eoption at the beginning.
- Leave eoption as a script and inherit choice from the base workspace. Hence, change the line choice = eoption; (in eapplication) to just eoption;
