[Octave-bug-tracker] [bug #37410] image.m has a wrong check for linearly-spaced x and y

[Francesco Potortì]

Follow-up Comment #3, bug #37410 (project octave):

Yes.  This is the code as I am currently using it:

  dx = diff (x);
  dy = diff (y);
  dx = std (dx) / mean (abs (dx));
  dy = std (dy) / mean (abs (dy));
  tol = 100*eps;
  if (any (dx > length(x)*tol) || any (dy > length(y)*tol))
    warning ("Image does not map to non-linearly spaced coordinates")
  endif

The only change is in the 'if' condition.
