Details:

"help contourc" displays the example below.


          x = 0:2;
          y = x;
          z = x' * y;
          contourc (x, y, z, 2:3)
             =>   2.0000   2.0000   1.0000   3.0000   1.5000   2.0000
                  2.0000   1.0000   2.0000   2.0000   2.0000   1.5000


The sources produce this result.


a = contourc (x, y, z, 2:3)
a =

   2.0000   1.0000   1.0000   2.0000   2.0000   3.0000   1.5000   2.0000
   4.0000   2.0000   2.0000   1.0000   1.0000   2.0000   2.0000   1.5000


Matlab doesn't match either result.


ans =

    2.0000    1.0000    2.0000    3.0000    1.5000    2.0000
    2.0000    2.0000    1.0000    2.0000    2.0000    1.5000
