常用命令：

• clc %清屏
• clear + 變數 %將變數擦除
• 註釋符：%
• 矩陣建立
  

邏輯語法

sum=0;i=1;
      while(i<=100)
       sum=sum+i;i=i+1;
       sum
      end

clear; clc; 
x = linspace(0, 10*pi, 100); 
y = sin(x); 
plot(x, y, 'b'); 
title({'this is a figure','and it''s', 'y=sin(x)'}); 

求積分

 syms x
 y1=
 
1/(1+x^4);
 y2=(x*exp(x))/(1+x)^2;
 y3=1/(x^2+2*x+3);
 fy1=int(y1)
 fy2=int(y2,0,1)
 fy3=int(y3,-inf,+inf)
