sys_char = evalc(sys);
sys_cell = splitlines(sys_char);
sys_cell = sys_cell(2:end-2);   %some useless empty lines
set(handles.text1, 'Max', 2, 'FontName', 'mono', 'String', sys_cell);

thank you! but error occured..

message is "input of evalc is not string or vector of char"

[Walter Roberson]

sys_char = evalc('sys');
