MATLAB: Previous Value of Numeric Edit Field

app designerMATLAB

Hi all,
Is there a quick way to reference the previous value of an App Deigner numeric edit field? This is in order to reset the value after an error dialog has been shown. Something like
app.NumericEditField.Value = app.NumericEditField.PreviousValue
would be ideal.
Many thanks.

I think thats almost what you'd want do have and store prevvalue during during successful calculation. Previousely in GUIDE and UIcontrol type construction there was a userdata field. I haven't been using appdesigner but it looks to be gone from a cursory inspection. However you can set a private/public property as a place to store the previous value upon successful computation run.
app.NumericEditField_N_PreviousValue= app.NumericEditField.Value
and 
app.NumericEditField.PreviousValue= app.NumericEditField_N_PreviousValue
during an error catch.
