Details:

The following code using contourf() fails in __contour__.m:
    x=1:10; y=1:20;
    [xx,yy]=meshgrid(x,y);
    z=xx.*xx+yy.*yy;
    contourf(z);

It works correctly with
   contourf(x,y,z);


I propose the following fix:

--- __contour__-orig.m  2010-05-31 09:46:26.000000000 +0200
+++ __contour__.m       2010-05-31 10:22:34.000000000 +0200

   if (length(varargin) < 5)
     z1 = varargin{3};
-    x1 = 1 : rows(z1);
-    y1 = 1 : columns(z1);
+    x1 = 1 : columns(z1);
+    y1 = 1 : rows(z1);
   else
     x1 = varargin{3};
     y1 = varargin{4};
