Hi Zheng you can handle your problem with followings; y=1+ 2*x + 3*x^2 yy=List[y[[1]],y[[2,1]],y[[3,1]]] yields -> yy={1,2,3} yy=List[y[[1]],y[[2,2]],y[[3,2]]] yields -> yy={1,x,x^2} See you later bna On Fri, 29 Sep 1995, Yuan Zheng wrote: > Hi, > > I used Matlab to do numerical computing for a long time.
