MatrixExpectation¶

class MatrixExpectation[source]¶

Bases: qiskit.aqua.operators.expectations.expectation_base.ExpectationBase

An Expectation converter which converts Operator measurements to be matrix-based so they can be evaluated by matrix multiplication.

Methods

`compute_variance`	Compute the variance of the expectation estimator.
`convert`	Accept an Operator and return a new Operator with the Pauli measurements replaced by Matrix based measurements.
