Lyapunov_Terra
当计算混沌系统Lyapunov指数时，gs.m代码实现正交化
直接运行L2.m，可计算出Lyapunov指数（该代码是基于奇异值分解计算Lyapunov指数的）
(chaotic system when calculating Lyapunov exponent, gs.m code directly Orthogonalization L2.m operation, translate into Lyapunov exponent (The code is based on the singular value decomposition Lyapunov exponent))
