Algebraic Signal Processing Theory: Cooley–Tukey-Type Algorithms for Polynomial Transforms Based on Induction

A polynomial transform is the multiplication of an input vector x∈Cn by a matrix Pb,α∈Cn×n, whose (k,[cursive l])th element is defined as p[cursive l](αk) for polynomials p[cursive l](x)∈C[x] from a list b={p0(x),...,pn-1(x)} and sample points αk∈C from a list α={α0,...,αn-1}. Such transforms find a...
