Driving data from GUI application to the matlab script

I am building a GUI application using App Designer. A button on the GUI invokes .m script(through callback) that has certain variables hard-coded and are used for the

execution of the script. These are the same variables I would want to drive through GUI(edit number field) to let the user decide the values and see the impact in results.

Let's say X is a variable within .m script and I want to change it through GUI. Tried this:

In .m script:

-------------

Before X is defined, added below line

app = app1; (app1 is the name of my GUI Application)

X = app.y; (where y is defined as a public property with no default values assigned in the GUI application)

In GUI application:

------------------

properties (Access = public)

y

end

function buttonPushed(app,event)

app.y = app.X_EditField.Value; (X_EditField is created as an entry using the Edit Field(Numeric) from Component Library)

run ('<.m>')

end

What am I doing wrong?

Why don't you create your matlab script as a function and then take y as an input argument?

function foo(y):
    % whatever your script needs to do with y
end

Put this function in the same location of your app or in a folder of matlab path, then in your app you can just call it

foo(y);
