基础实例代码
t=0:1/100:4*pi; y0=sin(3*t).*exp(-t/3); y= exp(-t/3); y1=0*t; subplot(2,1,1) %set sub pic position plot(t,y,t,-y,t,y0,t,y1); % draw pci load noisdopp; subplot(2,1,2) plot(noisdopp); syms n; result = limit(sin(n)/n,n,0);
画出的图为:

笔者尝试绘制三角函数与反三角函数
t=-pi/2:1/100:pi/2; y1=sin(t); y2=asin(t); plot(t,y1,t,y2);
画出的图如下:
