power_sum()

double MayaFlux::Nodes::Generator::Polynomial::power_sum ( const std::vector< double > &  coefficients, double  x  )

staticprivatenoexcept

Evaluates the coefficient list at x, highest power first.

Parameters

coefficients	Coefficient vector
x	Evaluation point

Returns

Sum of coefficient * x^k, accumulated from the last coefficient

The one loop behind create_polynomial_function and the live DIRECT evaluation of a node built from coefficients.
