# qiskit.ignis.mitigation.CTMPExpvalMeasMitigator.mitigation_matrix¶

CTMPExpvalMeasMitigator.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() $$A$$.

Paramètres

qubits (Optional[List[int]]) – Optional, qubits being measured for operator expval.

Renvoie
