[Octave-bug-tracker] [bug #48690] basic statistics functions should return NaN on empty input

[Nicholas Jankowski]

Follow-up Comment #9, bug #48690 (project octave):

ok, output for mode should follow:



>> [m f c] = mode(single([]))
Warning: MODE of a 0-by-0 matrix is NaN; result was an empty matrix in
previous releases. 
> In mode (line 72) 

m =
   NaN
f =
     0
c = 
    [0x1 single]

>> class(m)
ans =
single

>> class(f)
ans =
double


also verified that the others all only have one output  and do preserve
single/double status as well. will post patches shortly.
