The following uses specific examples to illustrate the meaning of subplot().

x1=0:0.02:10;
y1=2*x1.*exp(-5*x1);
x2=-4:0.02:4;
y2=5*sin(5*pi*x2);
subplot(2,1,1)  %创建2行1列第一个图形
plot(x1,y1,'b-'),grid on
xlabel('x'),ylabel('f(x)');
title('y1=2xexp(-5x)')
subplot(2,1,2) %创建2行1列第二个图形
plot(x2,y2,'r--','LineWidth',1),grid on
xlabel('x'),ylabel('f(x)');
title('y2=5sin(5\pix)')
