Currently I am able to create a GUI in the Matlab App Designer and I want to connect some of the input edit field value to some variable inside a .m file. How do I do that?
GUI:
function x_valueEditFieldValueChanged(app, event)
value = app.x_valueEditField.Value;
end
.m File:
want the variable x to be what the user input to be

Why not just call the function and pass that data as an input argument?
That would be by far the simplest and most efficient approach.

m-file:
function myFun(x)
disp(x);
end
GUI:
Properties
x
end
function x_valueEditFieldValueChanged(app, event)
app.x = app.x_valueEditField.Value;
myFun(app.x);
end

Hi @Kuang-Ting Hsueh
You can use ‘load’ function to load your desired variable from a matfile into workspace or a structure.
Here is more info on ‘load’ function Load variables from file into workspace - MATLAB load - MathWorks India.
Example:
S = load("matlab.mat"); %S is a structure
app.EditField.Value = S.myVar;
Hope this helps!

make x a property of the app. Have your callback do
app.x = app.x_valueEditField.Value;
