Re: Nd cell array

[David Bateman]

What about something like

#include <octave/oct.h>
#include <octave/Cell.h>

DEFUN_DLD (myvol, args, ,
  "-*- texinfo -*-\n\
@deftypefn {Loadable Function} address@hidden =} myvol (@var{n})\n\
\n\
Create @var{n} by 1 cell array of matrices\n\
@end deftypefn\n")

{
  octave_value retval;
  int n = args(0).nint_value ();
  Cell c (n,1);

  // Just fill with empty matrices for this test
  for (int i = 0; i <n; i++)
      c (i) = octave_value (Matrix (2, 2, 0));

  retval = c;
  return retval;
}
