matlab实现双线性插值算法,在界面上实现读取存放缩放图片-matlab bilinear interpolation algorithm to achieve, in the interface to read stored zoom picture

这个程序是为了实现图片（包括彩色图和灰度图）的放缩功能，能满足任意指定放缩倍数或任意目标尺寸，原理是依据双线性插值。-The code can shrink and zoom arbitray image to appointed multiple or size regardless of intensty image and color image, the key function relay on bilinear interpolation.
