可调Q因子小波变换，用在故障诊断中，程序中包含了原始TQWT工具箱和轴承振动信号信号的谱包络的求取等，最新的应用成果(Adjustable Q-factor wavelet transform used in fault diagnosis, the program includes a spectral envelope of the original TQWT toolbox and bearing vibration signal signal to strike, etc., the latest application of the results)

the code is based on lsb matching revisited technique the new technique available to the user for steganography. that provide high accuracy

this code is about tabu search optimization....

说明：  考虑一长度为D，宽度为L的理想均匀面阵天线，并用Matlab画出其二维波束方向图。(Consider an ideal uniform planar array antenna with length D and width L, and draw its two-dimensional beam pattern with MATLAB.)

将输入d进行扩张，方法是在d的每个数据中插入M-1个零值。 如输入d=[1,2,3,4] M=3 输出out=[1 0 0 2 0 0 3 0 0 4 0 0](To expand the input d, the method is to insert each data d, M-1 zero value. If the input d = [1,2,3,4] M = 3 output out = [1 0 0 2 0 0 3 0 0 4 0 0])
