fmpz_poly_deflate
Synopsis
#include <flint/fmpz_poly.h>void fmpz_poly_deflate(fmpz_poly_t result, const fmpz_poly_t input, ulong deflation)sourceSets result to p(x^{1/n}), where p is input and n = deflation, that is, keeps the coefficients of x^0, x^n, x^{2n}, \ldots. Requires that n \ge 1 divides fmpz_poly_deflation(input); other coefficients are dropped and the result is not necessarily normalised. Division by n = 0 raises an exception.
