How can I run a function on app designer using a push button?

I am attempting to run a function which can be run freestanding outside of app designer, however I have a few of the sam functions I would like to pair in a GUI. I keep getting the following error associated to the lines of code which follow it:

Error using Hip_Analysis_App
Too many output arguments.

Error in Interface_5_26_2020/HipButtonPushed (line 49)
app.Hip

Line 34-36:         function Hip(app)
            app.Hip = Hip_Analysis_App;
            end

Line 48: function HipButtonPushed(app, event)
           
Line 49: app.Hip

Any help resolving this issue would be greatly appreciated.

Based on the error message, it appears your function Hip_Analysis_App does not have any outputs. Check your function declaration in the file.

If it look like this

function Hip_Analysis_App

call your function in the app like this

Hip_Analysis_App;

Also note that the function has to be in the current folder or on the MATLAB path.

If your function is supposed to be returning a value, then update your function declaration to place the output variable in the declaration (out here)

function out = Hip_Analysis_App
