[Octave-bug-tracker] [bug #59950] exist function

[John W. Eaton]

Follow-up Comment #7, bug #59950 (project octave):

Interesting.  Here are two more to try:


exist (table({'foo','bar'}),'')
exist (table({'foo','bar'}),[])
exist (table({'foo','bar'}),table())


If those all return 0 and no error, then I guess the checks are done something
like this:


if (nargin == 1)
  if (isempty (first_arg))
    return false;
  else
    second_arg = "";  ## means search for anything
  endif
elseif (nargin == 2
        && (isempty (first_arg) || isempty (second_arg)))
  return false;
end
## Check argument types and do the real exist checks ...


If one or more of those fail, then maybe someone else can figure out an order
for the argument checks that is both simple and produces the same results as
Matlab.
