[Octave-bug-tracker] [bug #30950] wrong axes ranges in imagesc(x, y, z)

[Ben Abbott]

Update of bug #30950 (project octave):

                  Status:                    None => Patch Submitted        
             Assigned to:                    None => bpabbott

Follow-up Comment #1:

I've experimented with Matlab and found that the axis limits should be ...

  c = size (z, 2);
  xlim = 0.5 * ((x(end) - x(1)) * c / (c - 1) * [-1, 1] + (x(1) + x(end)));

  r = size (z, 1);
  ylim = 0.5 * ((y(end) - y(1)) * r / (r - 1) * [-1, 1] + (y(1) + y(end)));

This works for both equi-space x/y vectors and for sorted random x/y
vectors.

I've attached a changeset.

Testing would be appreciated.
