Problems with MaskDisplay command

Hi,

I've a simulink block and I set for it

disp('{\bf\it\fontsize{20}\fontname{Calisto MT}MODEL}', 'texmode','on'); 
port_label('output', 1, 'qpp'); 
port_label('output', 2, 'qp'); 
port_label('output', 3, 'q'); 
port_label('input', 1, 'u');

by the Mask Editor. Now I want apply it at a new block using matlab commands, I do:

set_param('sys/blockname', 'MaskDisplay', {'disp('{\bf\it\fontsize{20}\fontname{Calisto MT}MODEL}', 'texmode','on'); port_label('output', 1, 'qpp'); port_label('output', 2, 'qp'); port_label('output', 3, 'q'); port_label('input', 1, 'u')'})

it returns:

set_param('sys/blockname', 'MaskDisplay', {'disp('{\bf\it\fontsize{20}\fontname{Calisto MT}MODEL}', 'texmode','on'); port_label('output', 1, 'qpp'); port_label('output', 2, 'qp'); port_label('output', 3, 'q'); port_label('input', 1, 'u')'})
                                              |
Error: Unbalanced or unexpected parenthesis or bracket.

You can just execute what you're passing in as the third parameter to set_param to make sure that it's a string (and not a cell-array). I get the same error in MATLAB when I say:

>> {'disp('{\bf\it\fontsize{20}\fontname{Calisto MT}MODEL}', 'texmode','on'); port_label('output', 1, 'qpp'); port_label('output', 2, 'qp'); port_label('output', 3, 'q'); port_label('input', 1, 'u')'}

   {'disp('{\bf\it\fontsize{20}\fontname{Calisto MT}MODEL}', 'texmode','on'); port_label('output', 1, 'qpp'); port_label('output', 2, 'qp'); port_label('output', 3, 'q'); port_label('input', 1, 'u')'}
           |
  Error: Unbalanced or unexpected parenthesis or bracket.

Just from a cursory glance, the problem is that you are not escaping the quotes in the string. So you need:

   set_param('sys/blockname', 'MaskDisplay', 'disp(''{\bf\it\fontsize{20}\fontname{Calisto MT}MODEL}'', ''texmode'',''on''); port_label(''output'', 1, ''qpp''); port_label(''output'', 2, ''qp''); port_label(''output'', 3, ''q''); port_label(''input'', 1, ''u'')')
