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')'})

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'')')
