# qiskit.ignis.mitigation.CompleteExpvalMeasMitigator.assignment_fidelity¶

CompleteExpvalMeasMitigator.assignment_fidelity(qubits=None)

Return the measurement assignment fidelity on the specified qubits.

The assignment fidelity on N-qubits is defined as $$\sum_{x\in\{0, 1\}^n} P(x|x) / 2^n$$, where $$P(x|x) = \rangle x|A|x\langle$$, and $$A$$ is the assignment_matrix().
