Example of disp Function
The following MCode function shows how to use the disp function to print variable
values.
function x = testdisp(a, b)
persistent dly, dly = xl_state(zeros(1, 8), a);
persistent rom, rom = xl_state([3, 2, 1, 0], a);
disp('Hello World!');
disp(['num2str(dly) is ', num2str(dly)]);
disp('disp(dly) is ');
disp(dly);
disp('disp(rom) is ');
disp(rom);
a2 = dly.back;
dly.push_front_pop_back(a);
x = a + b;
disp(['a = ', num2str(a), ', ', ...
'b = ', num2str(b), ', ', ...
'x = ', num2str(x)]);
disp(num2str(true));
disp('disp(10) is');
disp(10);
disp('disp(-10) is');
disp(-10);
disp('disp(a) is ');
disp(a);
disp('disp(a == b)');
disp(a==b);
The Enable print with disp option must be checked.
