Paolo, alist = Array[a, 12] xlist = Array[x, 4] Evaluate[xlist] = Partition[alist, 3] It is necessary to use Evaluate on the lhs above, otherwise Mathematica resets xlist and not the parts of xlist. Then you can work with the individual pieces. x[2] {a[4], a[5], a[6]} David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: paolo tarpanelli [mailto:tarpanelli at libero.it] To: mathgroup at smc.vnet.net Given a time series x={a1,a2,a3,a4,a5,a6,...,an} how can i divide it in different segments x1, x2,..., xn x1={a1,a2,a3} x2={a4,a5,a6} ... xn={an-2,an-1,an} thanks Paolo
