sum along multiple dimensions

Follow-up Comment #2:

Changing category to Feature Request.  This is something that Matlab has added
relatively recently as you point out.

If you really want to use this functionality in your code in the meantime it
wouldn't be that hard to add an m-file to override sum().  Below is an example
which is also attached as sum.m


function s = sum (x, dim)

  if (nargin < 1 || nargin > 2)
    print_usage ("sum");
  endif

  if (nargin == 1)
    s = builtin ("sum", x);
  else
    if (! isnumeric (dim) || ! isvector (dim))
      error ("sum: DIM must be a numeric scalar or vector");
    endif
    s = builtin ("sum", x, dim(1));
    for i = 2:numel (dim)
      s = builtin ("sum", s, dim(i));
    endfor
  endif

endfunction
