给音频文件嵌入水印，用到了离散余弦变换，效果很好(Watermark to the audio file, use the discrete cosine transform, the effect is very good)

％ 本程序实现2维TM波FDTD仿真 ％ 此程序用PML设置吸收边界条件 ％ FDTD_2D_kongqi_PML ％ 仅喊有Ez,Hx,Hy分量( Of the procedures to achieve 2-D TM wave FDTD simulation this program set up with PML absorbing boundary condition FDTD_2D_kongqi_PML have only shout Ez, Hx, Hy component)

能够在一定TDOA估计误差下给出定位精度误差 /3d(this program can esitimate the location accuracy in 3D enviorenment when defing the tdoa error)

免疫算法，与遗传算法相似，只是多用了一个免疫函数；免疫算法是遗传算法的变体，它不用杂交，而是采用注入疫苗的方法。(Immune algorithm, similar to the genetic algorithm, but the use of an immune function; immune algorithm is a variant of genetic algorithms, it does not hybrid, but the use of vaccination method.)

tf*idf algoritm is a famouse algoritm in text mining.

从均匀PCM方法入手，产生一振幅为1和频率ω=1的正弦信号，分别用8电平和16电平进行量化，在同一坐标轴上绘出原信号和以量化信号，并比较这两种情况下的信号/量化噪声比(Starting from the uniform PCM method to produce a 1 amplitude and frequency ω = 1 of the sinusoidal signal, respectively, with 8 levels and 16 levels were quantified in the same plot of the original signal and the axes to quantify the signals, and to compare these two cases, the signal/quantization noise ratio)
