Baris,

With the function Select you can tackle these problems.

t={{1,2},{3,4},{5,6},{Indeterminate,Indeterminate},{8,9}}

Select[t,NumericQ[Plus@@#]&]

{{1,2},{3,4},{5,6},{8,9}}

The 2nd argument in Select adds the entities of the elements of t and
return False when the result in not Numeric.

Hope this helps

Maarten

Dear All,

I have been trying to remove some elements of a list which should be quite
straightforward. The list is as follows:

{{x1,y1},{x2,y2},.{xi,yi},{Indeterminate,Indeterminate},.{xn,yn}}. All the
components are real numbers apart from some Indeterminate expressions. I
want the list without the Indeterminate terms. I have been trying to use
Delete with If command but cannot succeed.

Can anyone help please?

Thanks
