I want to declare a global variable in matlab app designer's startup function in order to use it continuously through the app's code.

Specifically, I want to declare value1 as a global variable

I have tried that but it doesn't seems that works.

Thank you very much

Do not use global variables, especially in AppDesigner.

Instead, declare a public or private property accessible anywhere within the app or outside of the app (for public properties).

You're not declaring the property correctly. Check out the "step-by-step guide" link in my answer. It shows you pictures of each step.

Thanks for your reply!

What I was doing wrong was that I was putting in the button callback:

app.editnum.Value=value1; %INCORRECT

Instead of

app.editnum.Value=app.value1; %CORRECT

Thanks!
