IMSHOW(I,[LOW HIGH]) displays I as a grayscale intensity<BR> image, specifying the data range for I. The value LOW (and<BR> any value less than LOW) displays as black, the HIGH (and any<BR> value greater than HIGH) displays as white, and values in<BR> between display as intermediate shades of gray. IMSHOW uses<BR> the default number of gray levels. If you use an empty matrix<BR> ([]) for [LOW HIGH], IMSHOW uses [min(I(:)) max(I(:))]; the<BR> minimum value in I displays as black, and the maximum value<BR> displays as white.<BR><BR>根据说明是可以的,但是我试了一下也不行<BR>而且不光是IMSHOW(I,[LOW HIGH]) 不行<BR>imshow其他好多的显示方式都不行,郁闷死了
