XJ, Outer[#1[#2] &, {Sin, Cos, Exp}, {x, y}] {{Sin[x], Sin[y]}, {Cos[x], Cos[y]}, {E^x, E^y}} David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: Xiaoji Liu [mailto:chmlxj at hotmail.com] To: mathgroup at smc.vnet.net Suppose I have a list of operators {Sin, Cos}, and a list of variables {x,y}, I want to apply {Sin,Cos} on {x,y}, and the outcome to be {{Sin[x],Sin[y]},{Cos[x],Cos[y]}} I can achieve this by using Table function with a temporary counter i. But is there any way to do this without using temporary counters? Thanks, XJ
