speech recogniton code

the Ali_g_test is a simulink file for dc motor is to be used with Ali_PID_ga m file.

这是包含丰富内容的流行学算法工具，里面有大量的MATLAB仿真示例，希望对大家有帮助(It contains rich content tools for popular school algorithm, which has a large number of MATLAB simulation example, we want to help)

Methods to model communication channel

说明：  小波包分解重构后，求节点能量，matlab中运行很好(After the wavelet packet decomposition and reconstruction, the node energy is calculated, which runs well in matlab.)

天线方向图可以看出此算法的性能，该程序把静态方向图与加了旁瓣电平－30db的切比雪夫权方向图相比较(Antenna pattern can be seen the performance of this algorithm, the program direction of the static map with the addition of side lobe level of-30db Chebyshev right direction compared to Figure)

matlab学习，适合初学者对matlab软件进行学习(matlab learning software for beginners to learn matlab)

各种人脸识别的matlab程序，改动后可以跑得通。根据自己的需要进行选择。(Various face recognition matlab program, changes can run through. Choose according to their needs.)

说明：  利用MATLAB实现模拟退火算法计算商旅问题(Use MATLAB to achieve simulated annealing algorithm Business Problems)
