中文说明：matlab中自带imrotate和imsize函数可以实现图片的旋转和放缩，本程序不使用matlab自带函数，直接编程，使用最小邻近算法对图片放大、旋转进行编程。
English Description：
MATLAB imrotate and imsize function rotation and scaling of the picture can be achieved, since the program does not use MATLAB functions directly, picture zoom, rotate by using the algorithm of minimum adjacent programming.
