ocd函数 最优化的方法，呵呵，会有用的。没事的加油，哈哈(ocd is very important)

此程序为基于GM（11）的灰预测程序，进行数据预测，最少输入数据为两个(This procedure the gray prediction program based on GM (11), data predicted minimum input data into two)

This is a test code to show the spectrum of sine wave.

能量谱分析计算,小波包分析提取振动信号中的特征频率，关于神经网络控制。( Energy spectrum analysis and calculation, Wavelet packet analysis to extract vibration signal characteristic frequency, On neural network control.)

Quadrature amplitude modulation is a method of combining two amplitude-modulated signals into a single channel, thereby doubling the effective bandwidth. QAM is used with pulse amplitude modulation in digital systems, especially in wireless applications

这里主要对LMS算法及一些改进的LMS算法（NLMS算法、变步长LMS算法、变换域LMS算法）之间的不同点进行了比较，在传统的LMS算法的基础上发展了LMS算法的应用。(here on the main LMS algorithm and some improvements to the LMS algorithm (NLMS. modified LMS algorithm, transform domain LMS algorithm) between the different points of comparison, in the traditional LMS algorithm developed on the basis of the LMS algorithm application.)

层次分析法的求解程序，用于对数据进行层次分析(AHP solver for the analysis of the data hierarchy)
