[Octave-bug-tracker] [bug #64861] qr with single return value.

[Rik]

Update of bug#64861 (group octave):

         Planned Release:                    None => 10.1.0 (current default)

Follow-up Comment #4:

It has always been confusing that the output depended on the sparsity of the
input.  I think we should follow Matlab and guarantee that the one-output form
always produces the matrix R.  I marked the Planned Release as 10.1.

There is an easy fix, which is just to call triu() on the output X.  The
better fix, however, would be to change the code in liboctave/numeric/qr.cc so
that it returns the correct value from the raw Fortran results.
