# qiskit.opflow.primitive_ops.MatrixOp.primitive_strings¶

MatrixOp.primitive_strings()[source]

Return a set of strings describing the primitives contained in the Operator. For example, {'QuantumCircuit', 'Pauli'}. For hierarchical Operators, such as ListOps, this can help illuminate the primitives represented in the various recursive levels, and therefore which conversions can be applied.
