本程序可将输入的RGB图像转化为灰度图像！在Matlab环境下编程实现。-this procedure can be imported RGB images into gray image! Matlab programming environment.

最基本的由彩色图像转换为灰度图像的代码。在matlab中运行图像处理时用到的最基本源码，但是很多matlab中并不含有这个函数。-The most basic color images by gray-scale image is converted to code. In the matlab image processing used to run the most basic source code, but many do no
