This does what you want: Array[a, {2, 2}] /. a[i_, j_] :> Symbol[StringJoin["a", ToString[i], ToString[j]]] Alternatively you could miss out the Array[a, {2, 2}] step: Table[Symbol[StringJoin["a", ToString[i], ToString[j]]], {i, 2}, {j, 2}] Steve Luttrell <zhoukm at hotmail.com> wrote in message news:cj63a6$qpr$1 at smc.vnet.net... > With Array[a, {2,2}] I can get an array like: > | a[1,1] a[1,2] | > | a[2,1] a[2,2] |. > But occasionally I want matrix like: > | a11 a12 | > | a21 a22 | > I remember I once figured out a way to do it but now I forgot.
