模拟退火算法，常用的数值优化算法，适合初学者，非常方便(simulated annealing method, commonly used numerical optimization algorithm, for beginners, a very convenient)

当M=4时，QAM的蒙特卡罗仿真程序，绘出误符号率和误码率曲线，并和理论曲线比较。(When M = 4 Shi, QAM of the Monte Carlo simulation program, draw the symbol error rate and bit error rate curve, and and the theoretical curves.)

主要介绍了dvhop算法的源代码，先计算平均每跳的距离，再根据跳数求出锚节点与未知节点的距离，再用三边测量法求出未知节点坐标(Dvhop algorithm introduces the source code, to calculate the average distance of each jump, then jump a few calculated in accordance with anchor nodes and unknown distance from the node, and then calculated trilateration unknown node coordinates)

DIP text book kmeans image segmentation Input: ima: grey color image k: Number of classes Output: mu: vector of class means mask: clasification image mask

相比DeconvNet写得比较简洁易懂。但是原来代码里面给的数据似乎没法跑。所幸同作者还有一些代码用到了TCNN，比如action recognition，可以一起下载下来参考。这个代码主要特色就是tiled结构，可以用来参考，然后把里面ICA的优化函数换成RICA，Sparse Coding等等。总之，在这个代码里也了解了不少(比如line search等)。(DeconvNet well written and easy to understand compared to relatively simple. But the original code to the data inside can not seem to run. Fortunately, there are some code with the author uses TCNN, such action recognition, can be downloaded along down the reference. This code is the main feature tiled structure that can be used for reference, and then put inside the ICA optimization functions into RICA, Sparse Coding and so on. In short, this code can also learn a lot (such as line search, etc.).)
