构造一个空的双向栈，判断双向栈是否存在，出栈，入栈，判栈空，将栈置空，判栈满，取栈顶(Construct an empty two-way stack to determine whether there is a two-way stack, out of stack, stack, sub-stack empty, set the stack is empty, sub-stack is full, take the stack)

Lyapunov指数程序。适合初学者，可以直接通过替换方程，来进行计算。清晰实用。 (Lyapunov index procedure. For beginners, you can directly replace the equation to calculate. Clear and practical.)

MATLAB 的牛顿拉夫逊程序，里面有好几个节点求取潮流，已测试(MATLAB Newton Raphson procedure, there are several nodes strike trend has been tested)
