基于MATLAB平台的产生随机正交矩阵的函数，非常好-a numerical algorithm for generating a random symplectic orthogonal matrix

多刚体动力学matlb编程 用辛方法 Fully vectorized n-body equation nbodyVect(x0,dx0,mus,t) integrates the n-body equations of motion using either a symplectic second order integrator, or any of the standard built-in or user supplied first order integrators.

显式辛方法及传统显式rk法 解微分方程组，计算收缩导纳矩阵 主程序为duoji2 -Explicit symplectic method and the traditional explicit method for solving differential equations rk calculated admittance matrix contraction of the main program for the duoji2

完美的解算非线性最优控制问题，且该算法保辛，无须知道中间变量的值，对迭代初值敏感度较低-The optimal solution of the nonlinear optimal control problem, and the algorithm Paul symplectic, do not know the value of intermediate variables, iterative initial value of the lower sensitivity

详细的辛算法构造迭代文章及其代码，内容讲解深刻，代码很清楚(The detailed symplectic algorithm constructs the iterative article and its code, the content explanation is profound, the code is very clear)
