[Octave-bug-tracker] [bug #59403] integral2 and quad2d functions do not catch incorrect dimensions for matrix multiplication

[John W. Eaton]

Follow-up Comment #2, bug #59403 (project octave):

I changed the example to be


function r = fxy (x, y)
  size (x), size (y),
  r = sinc (x) * sinc (y);
end
integral2 (@fxy, -1, 1, -1, 1)


and I see


ans =

   15   15

ans =

   15   15

ans =

   15   15

ans =

   15   15

ans =

   15   15

ans =

   15   15

ans =

   15   15

ans =

   15   15

ans = 12.328


So, unfortunately, the integration function has selected X, Y values that do
conform for matrix multiplication.  So I don't see how we would detect an
error here.
