QC-LDPC码生成矩阵编程，围长为12，无4环(The program searches for a girth 12 QC-LDPC code given size of sub-matrix, row and column weights. The configuration of sub-matrices could also be changed. The program offers flexibility in constructing girth-12 QC-LDPC codes compared to other algorithms. The program builds a Tanner graph by connecting groups of rows and columns. A connection is made if it does not form less than twelve-cycles. The program may fail to find a code given particular parameters. It also does not find the smallest codes compared to other algorithms. )

一种光滤波器仿真设计.具有一定局限性.通过先行缔造滤波器频谱图,进行设计仿真(Simulation design of an optical filter has certain limitations. Plan first to create a filter spectrum, to simulate the design)

it a SCFDMA MATLAB source code

多种图像边缘检测方法研究源代码,对图像边缘检测方法进行了matlab仿真分析(The image edge detection methods)

signal processing using matlab (example)

【转】协同过滤代码，用于推荐系统，包括基于项目和基于用户两种情况。实现基于用户和基于项目的协同过滤算法。 实验所用数据为MovieLens – a web-based movies recommender system with 43,000 users & over 3500 movies. 保存在ga.mat文件用，由于ga.test测试集过于庞大，全部用来计算的话耗时庞大，所以每次计算时随机选择部分，具体函数的使用请参照probar.m。我所得到的实验结果保存在results1-results8.mat里面。([Turn] collaborative filtering code for the recommended system, including project-based and user-based two cases. User-based and project-based collaborative filtering algorithm. Experimental data for MovieLens- a web-based movies recommender system with 43,000 users & over 3500 movies. Saved in ga.mat file with Because ga.test test set is too large, all used to calculate the time-consuming massive, so every time The calculated random selection portion, the use of the specific function, please refer to probar.m. I obtained experimental results are saved inside results1-results8.mat.)

资料包括PSO，PSO-PID,PSO-AM,PSO-BP,FOA.通过粒子群能够很好的解决优化问题，对于学习PSO的初学者有很大的帮助，另外提供一个果蝇算法，望比对学习。(Data including PSO and PSO- PID, PSO- AM, PSO and BP, FOA.)

一个很好的matlab图像处理资料，希望对大家有帮助(A good matlab image processing information, we want to help)

用matlab实现语音识别，通过耳麦说出前后左右来控制及其运动(Speech recognition using matlab to achieve through the headset out and around to control the movement)

this is codes for membership functions in different fuzzy sets
