I=imread('C:\Documents and Settings\Administrator\桌面\a5.bmp');
bw1=edge(I,'prewitt');
imshow(bw1);
错误为：
??? Function EDGE expected its first input, I, to be two-dimensional.
Error in ==> edge>parse_inputs at 564
iptcheckinput(I,{'numeric'},{'nonsparse','2d'},mfilename,'I',1);
Error in ==> edge at 197

I必须是灰度图像或单色位图矩阵(二维矩阵)，不能是彩图矩阵(三维矩阵)。
在路径中出现中文不行吧
