This might have unintended consequences, e.g.: In[1]:= Outer[MapAll, {f, g}, {x[1], y[1]}] Out[1]= {{f[x[f[1]]], f[y[f[1]]]}, {g[x[g[1]]], g[y[g[1]]]}} while In[2]:= Outer[#1[#2] &, {f, g}, {x[1], y[1]}] Out[2]= {{f[x[1]], f[y[1]]}, {g[x[1]], g[y[1]]}} -- Andrzej Kozlowski Toyama International University JAPAN http://sigma.tuins.ac.jp http://eri2.tuins.ac.jp ---------- >From: BobHanlon at aol.com To: mathgroup at smc.vnet.net >To: mathgroup at smc.vnet.net >Subject: [mg19881] [mg19873] Re: [mg19819] F[f_,x_]:=f[x] ? >Date: Sun, 19 Sep 1999 01:20:55 -0400 > > Patrick, > > MapAll seems to work: > > MapAll[f, x] > > f[x] > > Outer[MapAll, {f, g}, {x, y}] > > {{f[x], f[y]}, {g[x], g[y]}} > > Bob Hanlon > > In a message dated 9/17/1999 10:58:23 AM, p_mclean at postoffice.utas.edu.au > writes: > >>What is the name of the in-built Mathematica function that plays the role >>of F in te following: >> >>F[f_,x_]:=f[x]. >> >>For example, >> >>Outer[F,{f,g},{x,y}] >> >>will give: >> >>{{f[x],f[y]},{g[x],g[y]}}. >> >
