Function applyMatrix2

Source 
pub unsafe extern "C" fn applyMatrix2(
    qureg: Qureg,
    targetQubit: c_int,
    u: ComplexMatrix2,
)
Expand description

Apply a general 2-by-2 matrix, which may be non-unitary. The matrix is left-multiplied onto the state, for both state-vectors and density matrices.

Note this differs from the action of unitary() on a density matrix.

This function may leave \p qureg is an unnormalised state.
