Details:

ndgrid() fails if one of its arguments is empty. For matlab compatibility, it
should return an empty matrix instead.

Here is what I get with Matlab R2012a:


>> x = ndgrid([]); whos x
  Name      Size            Bytes  Class     Attributes

  x         0x1                 0  double              

>> [x, y] = ndgrid([], []); whos x y
  Name      Size            Bytes  Class     Attributes

  x         0x0                 0  double              
  y         0x0                 0  double
