scicpp::polynomial::polypow¶

Defined in header <scicpp/polynomials.hpp>

Raise a polynomial to a power.

template<std::size_t pow, typename T, std::size_t N>
std::array<T, pow * (N - 1) + 1> polypow(const std::array<T, N> &P)¶

Polynomial coefficients are defined in a std::array P.

The power is the template argument pow.

template<ConvMethod method, typename T>
std::vector<T> polypow(const std::vector<T> &P, std::size_t pow)¶

Polynomial coefficients are defined in a std::vector P and the power is the function argument pow.

Return a std::vector of size pow * (P.size() - 1) + 1.

The template argument method define the method to use for polynomial multiplications either using direct convolution (scicpp::polynomial::ConvMethod::DIRECT, by default) or using Fast Fourier Transform (scicpp::polynomial::ConvMethod::FFT).
