在matlab中怎么进行指数函数的图解比较

1、命令行键入：% Define the meshx = 0:0.16:5;y = 0:0.16:5;[xx,yy] = meshgrid(x,y);% The plotzz = xx.^yy-烤恤鹇灭yy.^xx;h = surf(x,y,zz);h.EdgeColor = [0.7 0.7 0.7];view(20,50);colormap(hsv);title('$z = x^y-y^x$','Interpreter','latex')xlabel('x')ylabel('y')hold on

2、按“Enter”键。如图1所示。

5、命令行键入：plot([0:5 2 4],[0:5 4 2],'r.','MarkerSize',25);

6、按“Enter”键。如图3所示。

7、命令行键入：e = exp(1);plot([e pi],[pi e],'r.','MarkerSize&垆杪屑丝#39;,25);plot([e pi],[pi e],'y.','MarkerSize',10);text(e,3.3,'(e,pi)','Color','k', ... 'HorizontalAlignment','left','VerticalAlignment','bottom');text(3.3,e,'(pi,e)','Color','k','HorizontalAlignment','left',... 'VerticalAlignment','bottom');hold off;

8、按“Enter”键。如图4所示。
