matlab软件中生成文件夹，复制文件夹、文件和删除文件(matlab creat files copy files delete files.)

用卡尔曼卡尔曼滤波跟踪平面质点的运动，首先建立一个平面坐标系，则这个质点的运动要三个变量来描述(Kalman Kalman filter to track the movement of the plane particle)

It is about soving sparse solution from linear system, simpel and fast.

在matlab环境下利用LSB最低有效位算法将一个图片水印隐藏在载体图片中，并对被隐藏那个信息进行提取。(Matlab environment in the use of least significant bit LSB algorithm will be a picture watermark hidden in the picture carrier, and that information has been extracted hidden.)

说明：  关于Lorenz函数处于混沌时的图形，包括建立Lorenz函数集画图程序(about Lorenz)

constructive role of noise in signal detection from parallel arrays of quantizers.(A noisy input signal is observed by means of a parallel array of one-bit threshold quantizers,in which all the quantizer outputs are added to produce the array output.s(t)=s1(t)with prior probability P0,or s(t)=s0(t)with prior probability P1=1-P0 input signal-noise mixture x(t)=s(t)+n(t) x(t) is observed by means of a parallel array of M threshold comparators. yi(t)=U[x(t)+wi(t)-theta],i=1,2...M.wi(t) is threshold noise.Y(t)=y1(t)+y2(t)+...yM(t), the array output Y(t) is meansured at T distinct times.the plot is fthe theoretical value of minimal detection error probability Per varied with sigma.)

对信号进行小波包分解，得到节点的小波包系数。然后对每个节点系数进行重构。(Wavelet packet decomposition is used to get the wavelet packet coefficients of the nodes. Then the coefficients of each node are reconstructed.)

哈夫曼编码源程序，可以用于数据压缩的用处(Huffman source coding, data compression can be used for the usefulness of)
