[x,y]=meshgrid(-2:0.5:2,-2:0.5:2)
t=x.*exp(-x.^-y.^2)
[px,py]=gradient(t,0.05,0.05)
td=sqrt(px.^2+py.^2)
subplot(221)
imagesc(t)
subplot(222)
imagesc(td)
colormap('gray')
运行，无图象
??? Error using ==> image
Error using ==> image
Image CData can not be complex.

Error in ==> imagesc at 19
hh = image(varargin{1},'CDataMapping','scaled');

Error in ==> wangge at 6
imagesc(t)
。。。这是怎么搞的，用which imagesc 查到imagesc－M文件，没有新建过同名文件。
image和imagesc有何区别？
