基于PCA的人脸识别 Matlab代码 两种方法 KL 和kernel(PCA-based face recognition Matlab code)

基于PCA的人脸识别程序，内含有人脸库，非常不错的程序，适合初学者学习(PCA-based recognition program, containing someone face , very good program for beginners to learn)

直流电动机的所有相关例程的MATLAB/simulink仿真实例，对大家学习直流电动机有很大的帮助。(Dc motor all related routines of MATLAB/simulink simulation examples, is of great help for everybody to learn dc motor. )

文件是雷达设计使用的matlab源代码，其参考的是书籍《radar design with matlab》(document is designed to use radar Matlab source code, its reference books "radar design with Matlab")

说明：  高斯赛德尔和雅克比迭代求解方程的matlab程序(the Jacobi and GaussSediel )

基于Matlab的语音端点检测实验研究的按钮设计(Matlab-based Speech Endpoint Detection Experimental Study on the button design)

This letter presents a novel algorithm to compute the instantaneous frequency (IF) of a multicomponent nonstationary signal using a combination of fractional spectrograms (FS). A high resolution time frequency distribution (TFD) is defined by com-bining FS computed using windows of varying lengths and chirp rates. The IF of individual signal components is then computed by applying a peak detection and component extraction procedure

在MATLAB环境下的基于分水岭的分割算法，对初学者很有帮助。(Watershed-based segmentation algorithm, useful for beginners in the MATLAB environment.)

直方图提取函数，用于人脸识别中，输入一幅图像，函数内部对输入图像做短时傅里叶变换，得到四幅幅度图，再求四幅图的直方图特征，合并后输出(Histogram extraction functions for face recognition, the input image, the input image inside the function to do short-time Fourier transform, the four magnitude diagram, and then seek four graph histogram feature, the combined output)

matlab源代码 运行之后能够演凑卡农 很神奇的程序啊(matlab source code to run speech Minato Canon magical program)
