PCA_face_recognition-_Matlab

功能较全面的计算器，除了简单的四则运算之外，还增加了三角函数、幂函数和对数函数，另外还增加了shift功能键，可以用来计算反三角函数。使用方法：使用前将.m和.fig文件放到matlab工作目录下（本人R2013放到bin文件夹下）(More comprehensive calculator function, in addition to simple arithmetic, but also increased the trigonometric, exponential function and logarithmic functions, in addition to increasing the shift function keys can be used to calculate the inverse trigonometric functions. Usage: Before using the m and fig files into the matlab working directory (I R2013 into bin folder))

经典的压缩感知重建算法，可以很方便的使用。(it good)

基于LSB的直接4bit替换法，就是直接用秘密图像像素值的高4bit去替换载体图像像素值的低4bit。 (Direct 4bit substitution, that is, the direct use of the secret image pixel values of the high-4bit image pixel value to replace the carrier' s low 4bit.)

Turbo经典仿真链路，同前一链路相似但不同，加入了puncture功能！(Turbo classical simulation links, links with the former one is similar but different, joined the puncture function!)

MATLAB如何定义函数文件，对于使用matlab时，当发现没有合适的库函数，就需要自己定义函数了，此文档可帮助你(How MATLAB function definition file, for the use of matlab, when found no suitable library functions, you need to define your own functions, and this document can help you)
