Try: variable[a_String, i_Integer /; i ? 0] := ToExpression[a <> ToString[i]] variable["t", 3] // InputForm t3 variable["t", #] & /@ Range[13] // InputForm {t1, t2, t3, t4, t5, t6, t7, t8, t9, t10, t11, t12, t13} Cheers, Vittorio >-----Original Message----- >From: Heath Gerhardt [mailto:heathgerhardt at hotmail.com] To: mathgroup at smc.vnet.net >Sent: Monday, June 20, 2005 11:22 AM >Subject: [mg58163] [mg58156] lists of variables > >I need to make lists of variables, for example > >{t1,t2,t3} > >but have not been able to figure out how to make Mathematica do this. >Tried using > >Array[t,3] > >which gives > >{t[1],t[2],t[3]} > >but then I don't know how to set the t[i]'s in expressions similar to > >F[t[1]_,t[2]_,t[3]_]:=Cos[t[1]+t[2]-t[3]] > >thanks in advance >Heath
