关于电磁场中用超松弛法求网格电位位的matlab源代码 (Overrelaxation method using electromagnetic fields demand grid potential bit matlab source code)

基于粗糙熵和K-均值聚类算法的图像分割 (Based on Rough Entropy and K-means clustering algorithm for image segmentation)

说明：  通过使用matlab，对层次分析法进行求解，从而进一步确定权重，更快的解决问题。(By using matlab, the analytic hierarchy process (AHP) is solved to further determine the weight and solve the problem more quickly.)

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)

混合隶属度随机块模型，用于进行社区划分，检测重叠社区，节点分组等( Mixed-Membership Stochastic Block mold，which is a scalable approach to community detection that discovers overlapping communities in massive realworld networks.)

采用db4小波对是与信号进行降噪处理，实际效果良好(Using DB4 wavelet denoising is processing and signal, the actual effect is good)

this project about the Google ReCaptcha how it will work and all source code will be available in this code

复数计算，使用类来做的，可以选择自己要计算的方式(Complex calculation, using the class to do, and can choose their own way to calculate the)

说明：  自适应网格划分通用程序包，美国伯克利大学开发。(Adaptive Mesh generic package, the United States developed at the University of Berkeley.)

ics 的malloc实现，采用分离存储，模拟memory的malloc和free等操作。(to realize the molloc and free operation, the lab of ics class)
