一. colormap函数

可以使用colormap函数：

t1=[281.1,584.6, 884.3,1182.9,1485.2;
291.6,592.6,896,1197.75,1497.33;
293.8,596.4,898.6,1204.4,1506.4;
295.8,598,904.4,1209.0,1514.6];bar3(t1,1)
set(gca,'XTickLabel',{'300','600','900','1200','1500'},'FontSize',10)
set(gca,'YTickLabel',{'2','3','4','5'},'FontSize',10)
zlabel('Length (mm)','FontSize',10);
xlabel('Theoretical (mm)','FontSize',10);
ylabel('F','FontSize',10);% grid onfor i = 1:size(t1,1)for j = 1:size(t1,2)text(j*0.9, i*1.05, t1(i,j)*1.1, num2str(t1(i,j)),'FontSize',8);end
endcolormap summer
