Hi,
I have edittext and pushbutton.
If I write with "sym(' ')" for example a1 or R2 or alfa34...matlab works good. If I write any text in this format a1 into edittext, then I want to enable pushbutton.
But if the firts is number for example 1a or 45R or 89gama, then matlab generate error. So if I write any text in this format 2a into edittext, then I want to disable pushbutton.
Please, how Can I do this?
Thank you

Hi,
you can use isvarname for this purpose, something like
str = get(handles.edit1, 'string');
if isvarname(str))
set(handles.pushbutton1, 'enable', 'on')
else
set(handles.pushbutton1, 'enable', 'off')
end
Titus
