David G.Lowe的SIFT算子在Matlab环境下的实现，尺度不变的特征提取，并对两幅图片的特征点进行匹配，运行前要把siftWin32文件放在Matlab的win目录下，具体请参照README。默认为输入为灰度图像，要处理彩色图片请先转灰度rgb2gray() (The realization of SIFT operator David G.Lowe in the Matlab environment, the scale invariant feature extraction, matching and pictures of the two feature points, the siftWin32 file in the Matlab win directory to run before, please refer to the specific README. The default is the input for the gray image to color image processing, please turn gray by rgb2gray ())

Adaptive filtering constitutes one of the core technologies in digital signal processing and finds numerous application areas in science as well as in industry. Adaptive filtering techniques are used in a wide range of applications, including echo cancellation, adaptive equalization, adaptive noise cancellation, and adaptive beamforming. Acoustic echo cancellation is a common occurrence in today’s telecommunication systems. The signal interference caused by acoustic echo is distracting to users and causes a reduction in the quality of the communication. This paper focuses on the use of LMS and NLMS algorithms to reduce this unwanted echo, thus increasing communication quality.

matlab使用文本文件进行数据存取详细过程说明(matlab using a text file for data access detailed process description)

李耀锟：网上的例子虽然很多，但是大部分是介绍PDE工具箱自带的一些例子，这些例子中解的区域，边界条件是PDE工具箱已经编写好的，直接调用就可以。对于该如何自己设定求解区域及边界条件，却很少有人涉及。网上搜索发现只有刘平在博客中详细介绍过求解区域的设定。下面以一个椭圆型方程的例子来详细说明求解的各个步骤，希望对大家能有所帮助。(An elliptic equation numerical method with matlab)
