利用小波变换算法对灰度图像进行压缩,效果比较好( Carries on the compression using the wavelet transformation algorithm to the gradation image，and the effect is good. )

说明：  实现信号的功率谱估计，AR,MUSIC,FFT,周期图法(Achieve signal power spectrum estimation, AR, MUSIC, FFT, periodogram)

对雷达多脉冲回波进行匹配滤波处理后，再进行相参积累，提高检测信噪比(Coherent matched filter radar multi-pulse echo, to improve the detection signal to noise ratio)

DS-CDMA仿真-matlab代码，及其代码详细说明(DS-CDMA simulation-matlab code, and code details)

This matlab code is intended to demonstrate the physical significance/interpretation of the elements of diagonal matrix in Singular Value Decomposition (SVD). Here, multiple rows of a BIG matrix is gradually being filled with ones which means the information content is being reduced. Now, the eigenvalues and their 1st and 2nd derivatives are plotted.

包含1593手写体数字0 ~ 9。从semeion.data通过MATLAB semeion.mat，可以直接使用。 每一个行为样本，其中256是手写数字的16×16，在10栏的数字识别标签，例如：如果第一行是1，然后是0号，其次是1，1。等等。 在Matlab的小例子，可以得出每一个数字，一个更好的理解。你想翻转和旋转的是写作的习惯相一致的图像。(Contains 1593 handwritten digit 0~9. from semeion.data by MATLAB semeion.mat, can be used directly. In addition of MATLAB small example, can draw each digital, a better understanding of. The image you want to flip and rotation is consistent with the habit of writing.)

This function computes the RMS feature of the signals in x,which are stored in columns. The signals in x are divided into multiple windows of size winsize and the windows are space wininc apart. Inputs x: columns of signals winsize: window size (length of x) wininc: spacing of the windows (winsize) datawin: window for data (e.g. Hamming, default rectangular) must have dimensions of (winsize,1) dispstatus:zero for no waitbar (default) Outputs feat: RMS value in a 2 dimensional matrix dim1 window dim2 feature (col i is the features for the signal in column i of x)
