Hey guys,
Just a quick question about how to clear a numeric edit field. Ive tried using the following code to clear both a numeric edit feild and text area. This code doesnt work as an error pops up saying the 'Value' must be double scalar
Thanks :)

A numeric edit field cannot be blank. You can read more about the value properties of this component here.
MATLAB rejects the value if:
  • The value is NaN, blank, or a complex number.

Perfect, I did try that beforehand but with the 0 inbetween the ' ' marks, and it seemed to reject the whole button press.
Thanks again Cris!

Ah, putting it in quotes makes it text, resulting in the error message you were seeing.
