Apply a single-qubit generator with controls to the statevector.

Template Parameters

PrecisionT – Floating point precision of underlying statevector data
FuncT – Gate function type.
compute_indices – True if the controlled gate requires the computation of all statevector indices, otherwise only the 3rd and 12th entries are calculated (for optimization)

Parameters

arr – Pointer to the statevector.
num_qubits – Number of qubits.
controlled_wires – Control wires.
controlled_values – Control values (false or true).
wires – Wires the gate applies to.
core_function – Gate function returning the matrix-vector product for a wire block.
