Look up isempty(). And you probably want to wrap your warndlg inside a uiwait(). If it's like msgbox(), it will continue with your code, blasting right past that warning message unless you put it inside a uiwait().

I will need to do some testing to see when it is possible for the data to not be a cell array when it is retrieved. Unfortunately that is not something I can test from home with my current configuration.
I do not think you should be testing for the emptiness of the cells in the cell-clicked callback: if the user is editing a series of the cells, they are not going to want the calculations to take place until they are finished editing.
If you have the data and it _is_ a cell array and you want to ensure that there is something in each of the cells, then
any(cellfun(@isempty,data(:)))
will be true if there are any empty cells.
