Array of string cells and guide 'string'

I have in a GUIDE generated GUI several places where the user can enter data. This data is validated when the person clicks on a pushb button. Part of that validation is to check if the value makes sense and if not, to output an error message to a listbox in the figure.

So what I have done is:

error_msg = {''};

and I add error messages by doing

error_msg(end+1) = {'Error: something....'};

In the end, I do:

error_msg = error_msg(2:end)';
set(handles.status_text,'String', error_msg, 'Value', length(error_msg));

I was wondering if there is a better way to do this?

I don't see a better way. A slightly different way is:

error_msg=[];

error_msg=[error_msg;{'Error: something....'}];

set(handles.status_text,'String', error_msg, 'Value', length(error_msg))
