c = cconv (a, b, n) ¶c = cconv (a, b) ¶Compute the modulo-N circular convolution.
a and b are input vectors and c is the modolo-n
convolution of a and b. If n is not provided,
its assumed default value is length(a) + length(b) - 1,
which provides the same result as a linear convolution.
Examples:
cconv (1:2, 1:4) ⇒ 1 4 7 10 8
cconv (1:2, 1:4, 2) ⇒ 16 14
cconv (1:2, 1:4, 4) ⇒ 9 4 7 10
