说明：  利用matlab计算时间序列间的DTW距离(Using MATLAB to calculate DTW distance between time series)

能够利用matlab针对三芯光纤的干涉图样进行仿真，得到其干涉图片(Able to use matlab to three core optical fiber interference pattern, and simulation the interference image )

说明：  Matlab 实现 一维 PCA 压缩解压 图像，可以设置 eigen value 数目，观看压缩结果。(Matlab to achieve one-dimensional PCA-extracting compressed images, the number of eigen value can be set to watch the results of compression.)

两个l1准则下的噪声干扰信号压缩感知重构举例，两个例子的稀疏矩阵均为DCT矩阵，而观测矩阵分别采用单位阵和随机矩阵，有详细的步骤和使用方法，适用于初步的学习压缩感知方法。(This programme supply two examples by Compressed sensing with l1 norm. The sparse matrix of two examples are all DCT matrix and the obsever matrix are unit matrix and random matrix respectively. We give the detailed usage and steps for the programme which is useful to the beginner.)

通过Gabor原子库对语音信号进行处理，用到匹配追踪算法，对各种语音信号的仿真实验都很成功。(Gabor atoms is through the voice signal processing, matching pursuit algorithm is used, on the simulation of various audio signals are successfully.)

在图像传输时，常常需要对图像进行压缩，这些代码用来对图像进行压缩编码。(In the image transmission, it is often the need for image compression, the code used to image compression.)

用于压缩感知技术重建，本方法是滤波重建算法(Compressed sensing technology for the reconstruction, the reconstruction algorithm is to filter)

根据RBM深度网络（Hinton，2006）进行MINST手写文字的分类器的训练，利用训练得到的权值制作了这个小程序，通过这个程序可以看出训练结果对数据集内的测试样本和训练样本都能进行很好的识别，但是对其他的手写字体识别就没有那么好了。(According to RBM depth network (Hinton, 2006) conducted MINST handwritten text classifier training, using the training to get the right value to produce this small program, this program can be seen through the results of the training data set and the training sample test samples are can be well identified, but on the other handwriting recognition is not so good.)

计算色素占比，能够自动计算各种颜色的占比。省时省力。(Calculate the proportion of pigment, can automatically calculate the proportion of various colors. Saving time.)

本程序是基于二维最大熵的灰度图象分割，它考虑了两方面的因素：点灰度和邻域平均灰度。()
