```I'd like to eliminate the Indeterminate  (or other non-numerical terms,
as Infinite, etc...) items. Es.

x = {-1.25664, 0.628319, -0.628319, 1.25664, Indeterminate, -1.25664,
0.628319, -0.628319, 1.25664, Indeterminate};

or

x=Table[1/(3 - n), {n, 0, 5}])
{1/3, 1/2, 1, ComplexInfinity, -1,-1/2}

How can I do it with a simple command?
Many thanks, Roberto

Hi, Roberto,

Try this:

x = {-1.25664, 0.628319, -0.628319, 1.25664, Indeterminate, -1.25664,
0.628319, -0.628319, 1.25664, Indeterminate};
y = Table[1/(3 - n), {n, 0, 5}];

Select[x, NumberQ[#] &]
Select[y, NumberQ[#] &]

{-1.25664, 0.628319, -0.628319, 1.25664, -1.25664, 0.628319, \
-0.628319, 1.25664}

{1/3, 1/2, 1, -1, -(1/2)}

Have fun, Alexei
