comment Sampling a Chebyshev polynomial with the discrete cosine transform
@AnonSubmitter85 Can you say how I should zero-pad $a=[1,2,3]$ with three zeros? Do you mean that it should become either $[0,0,0,1,2,3]$ or $[1,2, 0, 0, 0, 3]$?

@KerrekSB Thanks Kerrek, your comment made me realized. The theorem says to perform the substitution (1 + x)^n p( (a + b x) / (1 + x) ). This implies that there is no division, and I can adapt Horner.

@KerrekSB, No, the coefficients of p(x) are randomly generated.
