EvaluateEvenPolynomialFxP operation


This documentation refers to the Classic QDK, which has been replaced by the Modern QDK.

Please see https://aka.ms/qdk.api for the API documentation for the Modern QDK.

Namespace: Microsoft.Quantum.Arithmetic

Package: Microsoft.Quantum.Numerics

Evaluates an even polynomial in a fixed-point representation.

operation EvaluateEvenPolynomialFxP (coefficients : Double[], fpx : Microsoft.Quantum.Arithmetic.FixedPoint, result : Microsoft.Quantum.Arithmetic.FixedPoint) : Unit is Adj + Ctl


coefficients : Double[]

Coefficients of the even polynomial as a double array, i.e., the array $[a_0, a_1, ..., a_k]$ for the even polynomial $P(x) = a_0 + a_1 x^2 + \cdots + a_k x^{2k}$.

fpx : FixedPoint

Input fixed-point number for which to evaluate the polynomial.

result : FixedPoint

Output fixed-point number which will hold $P(x)$. Must be in state $\ket{0}$ initially.

Output : Unit
