[Octave-bug-tracker] [bug #36749] contour causes abort with certain input

[Rik]

Update of bug #36749 (project octave):

                  Status:                    None => Invalid                
             Open/Closed:                    Open => Closed

Follow-up Comment #1:

Octave version 3.2.4 is very, very old and no longer supported.  Please update
to a newer version and re-run your code.  If there is still a problem then
this bug can be re-opened.

Incidentally, when I run your code on the latest stable version (3.6.2) I get
this:


octave-3.6.2:2> contour(d2(:,1), d2(:,2), d2(:,4))
error: __contour__: z argument must be a matrix
error: called from:
error:   /usr/local/share/octave/3.6.2/m/plot/private/__contour__.m at line
92, column 5
error:   /usr/local/share/octave/3.6.2/m/plot/contour.m at line 61, column 19


So part of the problem is that d2(:,4) is a column vector and not a matrix. 
You might be able to run contour correctly on version 3.2.4 if the third
argument to contour is a matrix.
