[Octave-bug-tracker] [bug #54143] Why can't issorted() work on matrices?

[Rik]

Update of bug #54143 (project octave):

              Item Group:                    None => Matlab Compatibility   
                  Status:                    None => Confirmed

Follow-up Comment #1:

Yeah, this doesn't really make sense.  Consider Matlab's description of the
issorted function (http://www.mathworks.com/help/matlab/ref/issorted.html).


If A is a vector, then issorted returns 1 when the vector elements are in
ascending order.

If A is a matrix, then issorted returns 1 when each column of A is in
ascending order.

If A is a multidimensional array, then issorted returns 1 when A is in
ascending order along the first dimension whose size does not equal 1.


They seem to be able to do it, we should too.
