Namespace: Microsoft.Quantum.Simulation

Package: Microsoft.Quantum.Standard

Multiplies the coefficient in a GeneratorIndex.

function MultiplyGeneratorIndex (multiplier : Double, generatorIndex : Microsoft.Quantum.Simulation.GeneratorIndex) : Microsoft.Quantum.Simulation.GeneratorIndex

Input

multiplier : Double

The multiplier on the coefficient.

generatorIndex : GeneratorIndex

The GeneratorIndex to be multiplied.

Output : GeneratorIndex

A GeneratorIndex representing a term with coefficient a factor multiplier larger.

Example

let gen = GeneratorIndex(([1,2,3],[coeff]),[1,2,3]);
let ((idxPaulis, idxDoubles), idxQubits) = MultiplyGeneratorIndex(multiplier, gen);
// idxDoubles[0] == multiplier * coeff;
