[Octave-bug-tracker] [bug #45739] sort 'descend' together with vectors created with the colon operator

[Michael Godfrey]

Follow-up Comment #3, bug #45739 (project octave):

a = 1:2:10  is a range,
>> typeinfo(a)
ans = range
>> whos
Variables in the current scope:

   Attr Name        Size                     Bytes  Class
   ==== ====        ====                     =====  ===== 
        a           1x5                         24  double


It is not a matrix. So, it appears
that sort is converting the range in a way that is
counter intuitive.


Matlab treats a = 1:2:10 as the matrix
a =

     1     3     5     7     9

>> whos
  Name      Size            Bytes  Class     Attributes

  a         1x5                40  double 

Matlab does not implement type range.  

So, one solution would  modify sort to convert range to
matrix (a = [a];).

About the priority this needs, I doubt if many users provide
range variables to sort. But, it should be fixed, especially
for matlab compatibility.
