你好，非常感谢你的回帖。只是我现在又出现了一个问题。
clc
clear
h=figure;
x=rand(1,10);
y=1:10;
plot(x,y,'r',x,y,'g');
set(h,'Linewidth',1.5)
saveas(h, 'test','jpg');


当给其加线宽时就报错 ...

GUI Alternative

Use File > Save As on the figure window menu to access the Save As dialog, in which you can select a graphics format.

x=rand(1,10);
y=1:10;
h=plot(x,y,'r',x,y,'g');
saveas(h, 'test','jpg');

h=figure;
x=rand(1,10);
y=1:10;
plot(x,y,'r',x,y,'g');
saveas(h, 'test','jpg');
