说明：  非正弦信号的波束形成程序，和利用相位的常规波束形成不同，非正弦信号的波束形成首先匹配滤波，提取包络，然后延时相加，(Non-sinusoidal signal beamforming process, and the use of conventional beam-forming phase is different from non-sinusoidal signals in the first match beamforming filtering, envelope extraction, and then add delay,)

在matlab环境下的向前和向后euler算法价偏微分方程问题(Matlab environment in the forward and backward Euler algorithm for partial differential equations the question of price)

文件夹LSB中是空域LSB算法程序，文件夹COX中是Cox算法主要程序，文件夹DCT中是频域加在中频的算法的程序。 步骤：把LSB，COX，DCT三个文件夹考在MATLAB目录下； 运行lsb_embed,programme,dct2_embed_mod即可。其中PSNR.m是计算峰值信噪比程序；attact.m & robust.m是攻击程序。(Content: folder LSB of spatial LSB algorithm program, folder COX Cox algorithm is the main program folder DCT frequency domain is added to the IF algorithm program. Steps: the LSB COX DCT three files folder test in the MATLAB directory run lsb_embed program, dct2_embed_mod can. The which PSNR.m calculate the peak signal to noise ratio procedures attact.m & robust.m exploit.)

Keogh的SAX聚集近似算法，首先采用PAA分段，然后正态化序列，在对应表上查询符号表示，这是一个很经典的时间序列表示方法(Keogh' s SAX gathered approximation algorithm, the first use PAA segment, then normal sequence, query on the corresponding symbol table indicates, this is a classic representation of the time series)
