    "abstract": "We consider the relation between the discrete coupled nonlinear\nSchr\\\"{o}dinger equation and Toda equation. Introducing complex times we can\nshow the intergability of the discrete coupled nonlinear Schr\\\"{o}dinger\nequation. In the same way we can show the integrability in coupled case of dark\nand bright equations. Using this method we obtain several integrable equations.",
