MATLAB R2014B:a = [0 1 0 0 0 1 1 1 0 0 0 1 0 1 1 1];colormap([0 0 0;1 1 1])imagesc(a)set(gca,'XTick',0.5:size(a,2)+0.5,'YTick',0.5:size(a,1)+0.5,... 'XTickLabel','','YTicklabel','','dataaspect',[1 1 1],... 'XGrid','on','YGrid','on','GridColor','k','GridAlpha',1) 如果用pcolor：a = [0 1 0 0 0 1 1 1 0 0 0 1 0 1 1 1];b = a;b(end+1,end+1) = 0;colormap([0 0 0;1 1 1]),pcolor(b)axis image ij off 每个格的中点分别是1.5 2.5 3.5 4.5 。怎么让它显示1 2 3 4a = [0 1 0 0 0 1 1 1 0 0 0 1 0 1 1 1];b = a;b(end+1,end+1) = 0;colormap([0 0 0;1 1 1]),pcolor(0.5:size(a,2)+0.5,0.5:size(a,1)+0.5,b)set(gca,'XTick',1:size(a,2),'YTick',1:size(a,1))
