GUI help in calling an if elseif else function
显示 更早的评论
Hi all,
I am trying to call out this if elseif else function in the GUI. So basically, the "what case box" represent the casenum, and the empty static box should call out a msg when "what case box" has a value.

Use the Callback property of the edit box to trigger the action. Remember that the edit box will be char (or cell array of char if Max>1 for the edit box) so you will need to str2double.
Note: you should not have any condition on the "else".

Thanks for pointing that out. I still keep getting this error message everytime I run it.

Please post the text as text and not as screenshot. Thanks.
The posted screenshot shows only a part of the error message. We need the full message instead.
After you have defined condition=str2double(...) you overwrite its value in the if block.

What is the result you expect from
str2double(set(handles.output, 'string'))
? Notice that is a set() call, not a get() call.
