粒子群优化算法

用matlab编写的一个解决0-1背包问题，其算法采用粒子群算法(use matlab software write 0-1 knapsack problem use PSO method)

一本介绍MIMO-OFDM的书，包括了MATLAB程序，非常适合做MIMO-OFDM仿真的参考书。(An introduction MIMO-OFDM books, including MATLAB program, very suitable for MIMO-OFDM simulation reference.)

数据库是由10个人的7种正面表情组成的213幅灰度图像，图像是以大小为256256的8位灰度级存储的，格式为.tiff型，平均每个人每种表情有2到4张。( the JAFFE database[11] which is composed of 213 images of female facial expression corresponding to 10 distinct subjects. Each image is stored at a resolution of 256×256 pixels and 8-bit gray level. Each subject in the database is represented with 7 categories of expression (angry, disgust, fear, neutral, sadness, happiness and surprise). )
