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

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)

I guess you want it in the callback. Simply try it.
