Hi Yu,

Assuming that you want to import data from MATLAB workspace into the App Designer, the below mentioned links would be helpful:

Hi:

Thanks for your reply.

The 'evalin' function can transfer the known variables from workspace to app, but the issue I faced is that, I need to know variable names that exist in the workspace.

for example, in cftool, you can see that once I launch the 'cftool', the variable names that exist in workspace are available in the dropdown list. how does this step be conducted?

Thanks!

I've got one way, you can try:

variable_names = evalin('base','who');

It'll return a cell array of the variable names in the workspace, then you can load specific data like this:

first_data = evalin('base', variable_names{1});
