Pick one: data /. {x_, y_} :> {f[x], g[y]} {f[#[[1]]],g[#[[2]]]}& /@ data Inner[#1[#2]&, {f,g},#, List]& /@ data MapThread[{f[#1],g[#2]}&,Transpose[data]] Bob Hanlon In article <b5uoth$lks$1 at smc.vnet.net>, Nathan Moore <nmoore at physics.umn.edu> wrote: << Subject: a little more complex list operation From: Nathan Moore <nmoore at physics.umn.edu> To: mathgroup at smc.vnet.net Date: Thu, 27 Mar 2003 11:56:33 +0000 (UTC) Thanks very much for all the previous replies. Another simple question - though I guess this will require more complex syntax. Suppose I have the list, data = {{x1,y1},{x2,y2},{x3,y3}} and I want to produce the result (for fitting/plotting) data2 = {{f[x1],g[y1]},{f[x2],g[y2]},{f[x3],g[y3]}} I assume that if there was only one transform I wanted to apply, f[x], then I could say data2 = f[data] but how about this more complicated transform with functions f and g? again thanks!
