I have a editable uitable in a GUI. How can I check the user input data, and if the values are negative, display an error message?

There's a CellEditCallback in which you can add whatever code you want in response to someone entering something in a cell of the table.

if any((data(:,1)) < 0)==1
warndlg('Must be greater than zero.','Warning!')
Where (data(:,1)) is column 1 of my uitable
I get the error:
Undefined function 'lt' for input arguments of type 'cell'.

Isn't 'data' a cell array from a uitable? In which case you need to apply cell operations or convert to a numerical array if it is pure numbers
