通过matlab来实现遗传算法，利用遗传算法程序和遗传算法工具箱来实现该功能，具体应用效果很好(Matlab achieved through the genetic algorithm, the procedure using the genetic algorithm and genetic algorithm toolbox to achieve the function of specific application of effective)

matlab编程实现非扭结样条插值函数，并调用matlab中的相关命令验证结果，绘出图形。(matlab programming of non-kink-spline interpolation function, and the related call matlab command to verify the results, draw the graph.)

周期图法谱估计需要对信号序列“截断”或加窗处理，其结果是使估计功率谱密度为信号序列真实谱和窗谱的卷积，导致误差的产生。本程序分别设计了周期图法,最大熵功率谱估计和Welch法以及它们的对比,最大熵功率谱估计目的是最大限度地保留截断后丢失的“窗口”以外信号的信息，使估计谱的熵最大。(Periodogram spectrum estimation signal sequence needs to " cut off" or add the window handle, the result is an estimated power spectral density of the signal sequence of the real spectrum and spectral convolution window, resulting in the generation of errors. The procedures were designed periodogram, maximum entropy power spectrum estimation and the Welch method and their comparison, the maximum entropy power spectrum estimation purpose is to maximize the retention of truncated after the loss of the " window" than the information signal, the entropy of the estimated spectrum maximum.)
