    _______________________________________________________

Details:

With statistics-1.2.4 package, when hist3 is called with centers higher than
any of the given data, the N output is not padded with 0 as it should.
For instance:


D = [1 1; 3 1; 3 3; 3 1]
D =

   1   1
   3   1
   3   3
   3   1


hist3(D, {0:4, 0:4})

error: surface: rows (Z) must be the same as length (Y) and columns (Z) must
be the same as length (X)


The solution is to add a size argument to accumarray. Patch attached.
