## @deftypefn {Loadable Function} {} sumsq (@var{x}, @var{dim})
## Sum of squares of elements along dimension @var{dim} of Galois array.
## If @var{dim} is omitted, it defaults to 1 (column-wise sum of squares).
##
## This function is equivalent to computing
## @example
## gsum (x .* conj (x), dim)
## @end example
## but it uses less memory.
## @end deftypefn

function varargout = sumsq (varargin)

  varargout = cell (1, max (1, nargout));
  [varargout{:}] = gsumsq (varargin{:});

endfunction
