说明：  此程序为DS-CDMA链路中加入基于子空间的PASTd多用户检测方法。系统中采用m序列阔频，可以通过高斯信道或瑞利信道。可以直接运行得到不同信噪比下的误码率曲线。(This procedure for the DS-CDMA link by adding space-based sub-PASTd multi-user detection methods. System m sequence used in wide-band, you can channel through the Gaussian or Rayleigh channel. Can be directly run different SNR BER curves.)

基于matlab的三角网条件平差，功能还不完善，还不能求点位中误差。(Matlab-based triangulation condition adjustment, the function is not perfect, it can not find the error point.)

基于PCA的人脸特征抽取，首先将200幅人脸图像转换成向量形式，进而进行组成样本矩阵。(The PCA-based facial feature extraction, first 200 face images into a vector format, then the composition of the sample matrix.)

An example that illustrates the importance of shift-invariance is image denoising by thresholding where the lack of shift-invariance causes pseudo-Gibbs phenomena around singularities.In addition to shift-invariance, it has been recognized that an efficient image representation has to account for the geometrical structure pervasive in natural scenes. In this direction, several representation schemes have recently been proposed
