张正友摄像机标定matlab程序，用来求出摄像机的内外参数矩阵。(Zhang Zhengyou camera calibration matlab procedures used to calculate the camera' s internal and external parameter matrix.)

说明：  提出一种受灰狼（Canis lupus）启发的新的元启发式方法，称为灰狼优化器（GWO）。 GWO算法模仿自然界中灰狼的领导等级和狩猎机制。(This work proposes a new meta-heuristic called Grey Wolf Optimizer (GWO) inspired by grey wolves (Canis lupus). The GWO algorithm mimics the leadership hierarchy and hunting mechanism of grey wolves in nature.)

数字图像处理中关于图像分割后跟踪的程序，可以是彩色图像。(Digital image processing, image segmentation and tracking program, you can color images.)

matlab开发环境下的语音波形的合成与识别，非常有用的一段程序的描述(Description waveform synthesis and voice recognition matlab development environment, very useful for some programs)

matlab滑动滤波程序，读入text直接实现滤波(failed to translate)

提取声音信号的MFCC特征参数，然后进行匹配，有训练语音，也有测试语音，测试信号既有训练过的，也有没训练过的，都可以识别(The MFCC feature parameters of sound signal are extracted and matched. There are both trained and tested voices. The tested signals can be recognized by both trained and untrained voices.)

In this model we take sums of u Xv and iteratively optimize parameters of the sums. For paper(s) see pd.hacker.lt

时兴的前推回代算法程序，可用于求解辐射状配电网三相潮流。(Forward-Backward Sweep algorithm for three-phase load-flow analysis of radial distribution systems.)
