RemoveUndefined( <List> )
Removes undefined objects from a list.
Example:
RemoveUndefined(Sequence((-1)^i, i, -3, -1, 0.5)) removes the second and fourth element of the sequence since expressions \mathrm{\mathsf{ (-1)^{1.5} }} and \mathrm{\mathsf{ (-1)^{2.5} }} are undefined and yields list {-1, 1, -1}.


Note:
