黄金分割法求极小，返回值fm为函数极小值，tm为极小值点，f为给定函数，t为函数变量，[a,b]为变量t的搜索区间(Golden section method is extremely small, the return value for the function fm minimum, tm for the minimum point, f for a given function, t for the function of variables, [a, b] for variable search interval t)

该 程序是将经验模态函数分解为特征模态函数的一种有效方法(emd is emperical module decomposition it can decompose the signal into characteristic signals and it is an effective method.)

说明：  上一届传下来的粒子群算法，需要进行优化的可以用这个程序(Particle Swarm Optimization )

Henon吸引子是混沌和分形的著名例子,迭代模型为xk+1=1+ax2k+byk,yk+1= xk.最常见的参数取值为a=1.4,b=0.3 .(The Henon attractor is chaotic and fractal famous example of the iterative model xk+1 = 1+ ax2k+ byk yk+1 = xk. The most common parameter values ​ ​ a = 1.4, b = 0.3)

cordic算法实现特征值分解，非常实用，代码可以作为参考(cordic eigenvalue decomposition algorithm, very practical, code can be used as a reference)
