I am working on a MATLAB GUI using App Designer, though perhaps my issue is similar to guide. What I would like to do is pass the output of one callback (button) into another.

The above suggests to me that you have a ui control button already that has the name loadmatButton and the handle to that is stored in app.loadmatButton . But then you are trying to save the results of the load() into app.loadmatButton, which would overwrite the ui control handle

Seems to me like you tackled it the wrong way.
Why isn't a simple property in app good enough?
As for your error, as Walter stated, you simply try to overwrite the button property with something not button. Simply add another property to app with a different name and set it there
