-
CompleteExpvalMeasMitigator.mitigation_matrix(qubits=None)[source]¶ Return the measurement mitigation matrix for the specified qubits.
The mitigation matrix \(A^{-1}\) is defined as the inverse of the
assignment_matrix()\(A\).- Parameters
qubits (
Optional[List[int]]) – Optional, qubits being measured for operator expval.- Returns
the measurement error mitigation matrix \(A^{-1}\).
