老外写的一份关于瞬时频率的算法程序及代码，很好很强大，十分值得一看哦。(Written by a foreigner on the Instantaneous Frequency algorithm program and code, very good very strong and very worth a visit oh.)

双向性渐进结构优化方法源代码,双向性渐进结构优化方法是YImin Xie教授提出的拓扑优化优化方法，是目前几种流行优化方法之一。(The code of Bidirectional progressive Structure optimization method.)

用迭代法求 x=根号a。求平方根的迭代公式为：X(n+1)=(Xn+a/Xn) /2。(Iterative method is used to find x = root a. The iteration formula for finding square root is X(n+1)=(Xn+a/Xn)/2.)
