matlab绘制函数 函数f(y)=3*y*log(y)-1/30*exp[-（30*y-30/e）^4] 怎么绘制啊?

命令：y=0:0。001:1;f(1,:)=3*y。*log(y)-1/30*exp(-(30*y-30/exp(1))。^4);f(2,:)=2。5*y。*log(y)-1/30*exp(-(30*y-30/exp(1))。^4);f(3,:)=2。5*y。*log(y)-1/36*exp(-(30*y-30/exp(1))。^4);f(4,:)=2*y。*log(y)-1/36*exp(-(30*y-30/exp(1))。^4);f(5,:)=2*y。*log(y)-1/50*exp(-(30*y-30/exp(1))。^4);plot(f,y);legend('1','2','3','4','5')   差不多的啊,哈哈
