funclist={Sin[x],x^3,Cos[x]^2}; Use Set rather than SetDelayed Clear[f]; f[x_]=funclist[[1]]; f[2] sin(2) or use Evaluate with SetDelayed Clear[f]; f[x_]:=Evaluate[funclist[[1]]]; f[3] sin(3) Bob Hanlon > > From: dmp55 at sympatico.ca To: mathgroup at smc.vnet.net > Subject: [mg65932] [mg65919] How to extract functions from a list and call them with any argument? > > I have a list of functions, i.e., > > funclist = {Sin[x], x^3, Cos[x]^2}. > > I can extract each of the functions, like > > In[1]:=funclist[[1]] > Out[1]=Sin[x] > > , but I don't know how to call these functions with a general argument. > If I type > > In[2]:=funclist[t][[1]] > > , I get > > Out[2]=t > > instead of Sin[t] (or t^3 or Cos[t]^2) > > What I would like is to extract a function from the list and to call it > with any argument, as it was defined in a standard way: > f[x_]:=Sin[x]. > > Dom > >
