Muhammad - please post the full error message (so that would be all of the red text that is generated when you run your above code).

The code you posted runs for me without error.
The sinc function is part of the Signal Processing Toolbox.
If don’t have the Signal Processing Toolbox, you can create your own version of sinc easily enough:
sincx = @(x) sin(pi*x+1E-8)./(pi*x + 1E-8);
x = linspace(-5,5);
y = sincx(x);
plot(x,y)
