三种角点提取方法的matlab程序，用于摄像机标定。(three methods of corner extract based on matlab。)

地球物理大地电磁测深的正演代码，包含了有限差分、有限元等(magnetotelluric 2D forward finite element program)

有效实行数据分类和图像分割的源码， 非常适合学习实用(image and data segmentation)

imfreqfilt函数 对灰度图像进行频域滤波 参数I 输入的空域图像 参数ff 应用的与原图像等大的频域滤镜( imfreqfilt function for gray image frequency domain filtering Parameters I entered the airspace image)

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)

基于粗糙集的特征选择Matlab源程序。(Feature selection based on rough set.)

此程序使用MATLAB实现 利用升余弦滚降特性来检测信道质量(This program uses MATLAB implementation using raised cosine roll-off characteristics to detect the channel quality)

This is a fault data from bearing.

针对约束优化问题，采用MATLAB编辑的源代码程序(For constrained optimization problems using MATLAB editing source code program)
