I have a problem about calculating with Delta Function. I am trying write matlab code for these function.
I wrote the following code for this function.
n = -5:1:7;
x = delta(n+1) - delta(n) + unit(n+1) - unit(n-2);
axis([-6 8 -1.5 1.5])
But I am getting the following error.
I don't now how can ı write the delta function in this way ,
function y = unit(x);
y = zeros(size(x));
y(x>0) = 1;
Can you help me write the delta function as the 'unit' function you see above? Thank you for your helping.

If you have the Symbolic Math Toolbox, use the dirac function. It can be used with non-symbolic arguments as well.
