In[122]:= f[x_] := x[[1]]+x[[2]]+x[[3]] In[123]:=data = Table[x*y,{x,5},{y,3}] Out[123]={{1,2,3},{2,4,6},{3,6,9},{4,8,12},{5,10,15}} In[124]:=Map[f[#]&,data] Out[124]={6,12,18,24,30} If these are not the specifics of your problem or your data, why not post a specific example? -- Paul Lutus www.arachnoid.com
