详细介绍了在MATLAB环境中，MAT文件的编辑与读写，通常使用load和save两个命令进行 MAT 文件的读和写(Described in detail in the MATLAB environment, MAT files editing and read and write, load and save commonly used two commands to read and write MAT files)

程序用matlab实现基于模板和肤色的人脸检测,首先利用肤色信息检测出可能的人脸区域,然后进行模板匹配.可以实现一幅图片中多人脸的检测.(procedures using Matlab based templates and color of face detection, the first to use color information may detect a face, then template matching. can be achieved over a picture of face detection.)

matlab学习的最好资料，可以看看，参考参考，学习进步。(matlab learn the best information, you can see, reference information, study progress.)

说明：  各种测试函数的源代码，包括ackleysfunction、braninfunction等(Various test functions of the source code, including ackleysfunction, braninfunction etc.)

此代码可以进行指纹识别，包括预处理，特征提取，分类识别(this code can fingerprint identification, including preprocessing, feature extraction, classification, etc.)
