> I want it should work on matlab workspace .
Bad idea. This defeats the purpose of an app which is to allow users to interact with data from the app rather than requiring users to manually create and manipulate data in an independent workspace. That approach is not reproducible and very prone to error.
- Where do those variables come from? If you're loading a mat file or reading a data file, do that directly within the app.
- If the file source is to be selected by the user, include an app component that allows the user to select the file (see uigetfile).
- If you're manually defining variables and variable names in an external workspace and the app needs those variables, you have to rethink that process and create a way for users to enter parameters directly within the app so the app can do that work within callback functions.
The solution involves reworking the workflow. If you run into a problem implementing those changes, specificily explain the source of the data, the workspace the data exists in, and explain why that isn't being done within the app.
