matlab实现的灰度处理方法，是一篇很好的文献(matlab realize the gray-scale approach is a good literature)

quadtree implementation in matlab

飞思科技《Matlab7基础与提高》书籍源码，希望对大家有用(Fly think technology "Matlab7 foundation and improve" books, the useful source code)

【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.)

Hinf 的源程序，Hinf是鲁棒控制领域的经典算法，程序经调试可以用。(Hinf of the source, Hinf robust control area is the classic algorithm, the program can be used by the debugger.)

一个数学公式的简单应用在matlab中的实现，绝对值及平方等(Simple application of a mathematical formula in the matlab implementation, such as absolute value and square)

This is code to simulation of AM, FM, PSK, QAM modulation

分别使用MVDR、Root-Music和ESPRIT三种方法对信号频率估计进行仿真实验，其中噪声为复正弦加性白噪声，给出正弦信号频率的估计值。(Using MVDR, Root- Music and ESPRIT three methods to estimate the signal frequency simulation experiment respectively, which is suitable for complex sinusoidal additive white noise noise, sine signal frequency estimate is given.)

M-file for simulating a QPSK transmitter by modulating with a pseudo random bit stream. A serial to parallel conversion of the pseudo random bit stream is performed with mapping of two bits per symbol. A cosine and sine carrier is configured and the I and Q symbols modulate these carriers. The I and Q carriers are combined and time and frequency domain plots are provided showing key waveforms at various positions in the QPSK transmitter.
