Two minute video shows how to validate GUI input. This makes sure that user input will not break your code. This example makes sure that the edit box value is not greater than twelve. This technique can be used for many different tests.

It is a fine Exampla but the code line: set(hObject, ‘String’, ‘12′); is IMO not realy adecuate.
These kind of declarations will produce “other errors” soon or later… I find better something like:
set(hObject, ‘String’, num2str(modeNum) );
so wenn you mustchange the treshold value you shuoldf change only one value, isn’t it?

José,
I totally agree with your idea here. In my video series “Cleaner Code in MATLAB”

I talk about how you should avoid the use of Magic Numbers. Sometimes I do things for brevity in the videos that I could do better with more time.
Thanks! Doug

Ken,
Thank you, the file was corrupted. I have verified the fix is working now.
Thanks, Doug
Wrap code fragments inside <pre> tags, like this:
<pre class="code"> a = magic(3); sum(a) </pre>
If you have a "<" character in your code, either follow it with a space or replace it with "<" (including the semicolon).
