Global variables in Matlab app

Hi,

How to specify global variables in Matlab app?

I need to access both symbolic and numeric variables across funtions within a Matlab app. So, I thought of creating global variables. I created a startup function and declared my global variables in there. But for some reason they are not global and are not accessible outside of my startup function.

Thanks in advance for the suggestions.

Thanks,

Abinav.

Why do you want to use global variables? Why are the other strategies of sharing data between functions not working?

[Abinav]

It's not a usual function. It's a Matlab app and I want to transfer data between 1 call back function to other (1 button press function to other). I don't know other ways of transfering data except global variables. Besides, it's the same variable that is being used in both the call back functions.

Create a property to store the value.

For transferring data between one callbacks function to another, you can use “properties” which can be accessible to all functions and callbacks in an app.

"Public Properties" are accessible both inside and outside the app, whereas private properties are only accessible inside of the app.

Refer to the documentation on Share Data Within App Designer Apps for further details on defining properties.
