1. 基本命令
clc;clear;close all;
t=linspace(0,2*pi,100);
y=sin(t);
plot(t,y)
基本图像
修改命令以及美化命令如下：
titlelabelplot
plot(t,y,'linestyle','-')
在这里，
linestyle表明绘图线型为实线，当然，这里可以使用更多命令，比如 线宽(linewidth,3)、线的颜色(color,'r')等
完整的表述plot(t,y,'linestyle','-','linewidth',5,'color','r')
label
完整的表述为
xlabel('time','fontname','Arial','fontsize',18,'fontweight','bold')
以及标签的位置
xlabel('time','fontname','Arial','fontsize',18,'fontweight','bold','position',[pi -1.11])
ylabel('sin(t)','fontname','Arial','fontsize',18,'fontweight','bold')
figure 2
clc;clear;close all;
t=linspace(0,2*pi,100);
y=sin(t);
plot(t,y,'linestyle','-','color','r','linewidth',5)
xlabel('time','fontname','Arial','fontsize',18,'fontweight','bold','position',[pi -1.11])
ylabel('sin(t)','fontname','Arial','fontsize',18,'fontweight','bold')
title('y=sin(t),'fontname','Arial','fontsize',18,'fontweight','bold'')
