Curry Taylor : > I have (for simplicity) something like this: > > f[x_, y_] := x+y; > > I want to use this function for a variety of parameters in a list: > > indices = {{a,b}, {c,d}, {e,f}, ..} > > so that I get > > {a+b, c+d, e+f, ..} > > Doing the intuitive thing (for me) > > f /@ indices > > results in > > {f[{a, b}], f[{c, d}], f[{e, f}], ..} > > but what I want is > > {f[a, b], f[c, d], f[e, f], ..} > > and that's not what I'm getting. I have tried using Flatten, pure > functions (Slot # and &), different Map functions, nesting at parameters > (like {1} and {2}), and other things but I just can't seem to get what I'm > after. Any help please? > > Thank you, > > Curry Just change the definition of your function as follows f[ {x_,y_} ]:=x+y indices={{a,b},{c,d},{e,f}}; Map[f,indices] {a+b,c+d,e+f}
