先定义几个变量:- _- z9 D; I& D
x = 0:pi/10:2*pi;

matlab作图的时候,如果直接使用plot(x,y1,x,y2,x,y3);那么matlab将自动使用不同的颜色来区别这三条曲线。

% W* N& y# l9 R7 Y7 H, C: T但是有的时候,为了保证黑白打印的时候也能区分不同曲线,就要用不同线型来区分。怎么样让matlab自动做这件事呢。+ w9 ^. e3 u" ~( C7 Z" o4 @
" d; S+ J5 i9 o9 CYou can configure MATLAB defaults to use line styles instead of colors for multiline plots by setting a value for the axes LineStyleOrder property using a cell array of linespecs. For example, the command set(0,'DefaultAxesLineStyleOrder',{'-o',':s','--+'})defines three line styles and makes them the default for all plots. To set the default line color to dark gray, use the statement set(0,'DefaultAxesColorOrder',[0.4,0.4,0.4]);0 i, z- F/ _ Y# R1 \
也就是说在plot(x,y1,x,y2,x,y3);的前面加上这两句话,set(0,'DefaultAxesLineStyleOrder',{'-o',':s','--+'})set(0,'DefaultAxesColorOrder',[0.4,0.4,0.4]);这回效果如下:
