| Bug report for Octave 2.1.31 configured for %OCTAVE_CANONICAL_HOST_TYPE%
| 
| Description:
| -----------
| 
| The order of parameters for plot/contour.m differs from that in matlab
| To make it the same, it must be changed from contour(z,n,x,y) to
| contour(x,y,z,n).

OK, I applied this patch.  I suppose some people will complain about
the incompatibility with previous versions of Octave.  Hmm.
