Example usage

matrix = UnitaryMatrix(
    u00=0.19509,
    u01=-0.98079,
    u10=0.98079,
    u11=0.19509
)

decomposer = GateDecomposer(matrix)
angles = decomposer.decompose()

if angles:
    # Verify the decomposition
    if decomposer.verify_decomposition(angles):
        print("Decomposition successful!")
