Like what is the syntax for delta in matlab?
MATLAB does not have the delta operator. The suggested dirac() does not work for this purpose:
n = [-1 0 1]
dirac(n)
dirac(sym(n))
but your delta function should be 1 at parameter 0.
You need to define it yourself, such as
delta = @(x) double(x==0);
delta(n)
