# qiskit.aqua.operators.state_fns.CVaRMeasurement.compose¶

CVaRMeasurement.compose(other, permutation=None, front=False)

Composition (Linear algebra-style: A@B(x) = A(B(x))) is not well defined for states in the binary function model, but is well defined for measurements.

Paramètres
• other (OperatorBase) – The Operator to compose with self.

• permutation (Optional[List[int]]) – List[int] which defines permutation on other operator.

• front (bool) – If front==True, return other.compose(self).

Type renvoyé

OperatorBase

Renvoie

An Operator equivalent to the function composition of self and other.

Lève

ValueError – If self is not a measurement, it cannot be composed from the right.
