Find indexes of variables in vector

I need to find indexes of variables in vector which are eg. out of my set range.

Range eg. from 600 to 2000

Vector of 1000 variables and I need only indxes of that variables which are out of this range.

Any ideas?

If x is your vector, then

idx = (x<600) | (x>2000);

is a logical index pointing to the out-of-range values.

If you need the actual positions,

idx = find((x<600) | (x>2000));

Thanks cyclist. Didn't realize you could use | or & in the find command.
