How to run a matlab function using a button pushed in AppDesigner

Hello everyone,
My question is simple. I want to run a function in matlab base workspace using a button pushed in AppDesigner.
I added a button in my app, and create a callback with this instruction :
run ('Path of my function');
My function is (just for the test) :
function r=addition(a,b)
r=a+b;
end
Thank you in advance.

Using assignin to create variables in the base workspace and calling a script is a shot in your knee. Convert the script into a function and provide the variables as input arguments. Then it is very easy to call your function from inside the callback of a GUI.

The typical way would be to invoke addition() from your callback the way you would from any ordinary function,
function ExecuterButtonPushed(app,event)
a=app.aEditField.Value;
b=app.bEditField.Value;
r=addition(a,b);
end

Maybe it will be more clearly with this explanations.
I'm afraid not. What you have not explained is why the machine you are controlling needs to receive its instructions from a Matlab script as opposed to an mfunction. As Jan points out, you could easily convert your script to a function and invoke that function directly from the callback, as my original answer suggests.
Also, even if you insist on using a script, it is not clear what problems you are currently experiencing by running your script from the callback. I can only guess it is because there are additional variables that the script needs besides the EditField values and which reside in the base workspace. If so, why not just bring those extra variables into the app where the callback can see them? Make them inputs to the app constructor and store them in properties.
