<FONT FACE="Times New Roman">MATLAB </FONT>有许多的绘图选项，以下一一做介绍。如果要将二条曲线划在同一个图，可参考以下的例子：
<P>
<FONT COLOR=#FF0000 FACE="Times New Roman">>> x=linspace(0,2*pi,30);</FONT>
<P>
<FONT COLOR=#FF0000 FACE="Times New Roman">>> y=sin(x);
z=cos(x);</FONT>
<P>
<FONT COLOR=#FF0000 FACE="Times New Roman">>> plot(x,y,x,z)
% </FONT><FONT COLOR=#FF0000>将</FONT><FONT COLOR=#FF0000 FACE="Times New Roman">
y=sin(x) </FONT><FONT COLOR=#FF0000>及</FONT><FONT COLOR=#FF0000 FACE="Times New Roman">
z=cos(x) </FONT><FONT COLOR=#FF0000>二函数分布绘图</FONT>
<P>
<FONT COLOR=#FF0000 FACE="Times New Roman">>> plot(x,y,'g:',x,z,'r--')
% </FONT><FONT COLOR=#FF0000>加上不同的颜色及符号来区别二条曲线
