## @code{finite} is deprecated and will be removed in Octave version 4.4.

## Return a logical array which is true where the elements of @var{x} are
## finite values and false where they are not.
## For example:
##
## @example
## @group
## finite ([13, Inf, NA, NaN])
##      @result{} [ 1, 0, 0, 0 ]
## @end group
## @end example
