Time series
x=ToExpression[Table["a"<>ToString[k],{k,12}]]
{a1,a2,a3,a4,a5,a6,a7,a8,a9,a10,a11,a12}
Subdivision length
m=3;
Define new variables
Evaluate[ToExpression[Table["x"<>ToString[k],{k,Length[x]/m}]]]=
Partition[x,m];
Check
x3
{a7,a8,a9}

<< 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}
