DOST extraction code

本资源为自己编写的遗传算法求多元函数极值的Matlab程序，共大家共同学习和研究。(This resource is to write your own genetic algorithms for multi-function extreme Matlab program, a total of common learning and research.)

说明：  对海浪数据处理得到海浪谱。可以模拟不同风速产生的海浪谱，并得到一维海面分布。(Propose the wave hight data and spectrum analysis.Wave spectrum generated by different wind speeds can be simulated and one-dimensional sea surface distribution can be obtained.)

实现产生伪随机序列的部件 —— 线性反馈移位寄存器单元。 SFlog2为扩频因子的底数为2的对数值，cycle为PN序列的周期，其值为2^SFlog2。initial_state为移位寄存器的初始状态，generator_polynomial_coefficient为生成PN序列所需的本原多项式，对应于移位寄存器的连接向量。(The realization of pseudo-random sequence generated components- LFSR unit. SFlog2 factor for the spread-spectrum base 2 of value, cycle for the PN sequence cycle, its value is 2 ^ SFlog2. initial_state shift register for the initial state, generator_polynomial_coefficient to generate the necessary PN sequence primitive polynomial, corresponding to the shift register connection vector.)

pam算法，能够帮助用户理解pam算法的思想，更好的理解该聚类思想(PAM algorithm, can help users understand the thoughts of PAM algorithm, a better understanding of the clustering thought)

搭建的双馈风力发电机变流器控制模型，我自己做项目的时候用过，效果很好，大家可以随便用。 (Converter control model of doubly-fed wind power generator, I was working as a project, the effect is very good, you can literally use. )
