I need to make a GUI in which different functions can be selected from a pop-down menu to work with data already loaded into the workspace. I just need to know the syntax in the m file for the gui:

if (function name) in list is selected

use this function

Apologies, this is a basic question, I have tried looking it up for a while and couldn't find anything. Thanks

Thanks for the reply, sorry for the delay, I thought an email would be sent when it was answered. How do I put this code under the Callback(hObject... or CreateFcn(hobject... ? thanks

在 MATLAB Online 中打开

List     = {'sin', 'cos', 'tan'};  % String of the listbox
Value    = 2;                      % Value property of the listbox
Selected = List{Value};
Data     = 1.1415;                 % "data already loaded into the workspace"
result   = feval(Selected, Data)
