刚接触matlab，帮我画幅图
 

小弟刚刚接触matlab，请问哪位高人帮我画幅图
S =
(-epsilon^4*sin(309/1250)+3*epsilon^2*sin(309/1250)+epsilon^4+epsilon^2)/(-sin(309/1250)+1-epsilon^2*sin(309/1250)+epsilon^2)
范围-1到1 plot（epsilon,S）

syms epsilon
s=(-epsilon^4*sin(309/1250)+3*epsilon^2*sin(309/1250)+epsilon^4+epsilon^2)/(-sin(309/1250)+1-epsilon^2*sin(309/1250)+epsi...[/QUOTE]
t=-1:0.1:1;
plot(t,s)

不知道对你有没有参考价值

这个...不行吧

都不知道该怎么说了，这是我在粘贴你的程序。因为这个式子本身不需要改。因为引用你的程序回复，所以就会出现...[/QUOTE]
