Polynomial Convolution
Convolution and polynomial multiplication.
conv(x, y)
x, y |
real or complex vectors. |
r = conv(p,q) convolves vectors p and q.
Algebraically, convolution is the same operation as multiplying the
polynomials whose coefficients are the elements of p and q.
Another vector.
conv utilizes fast Fourier transformation.
conv(c(1, 1, 1), 1) conv(c(1, 1, 1), c(0, 0, 1)) conv(c(-0.5, 1, -1), c(0.5, 0, 1))
