function x = nnsumr(x)
%NNSUMR Sums each row of a matrix.
%  
%  This function is obselete.
%  Use SUM(M,1).

nntobsf('nnsumr','Use SUM(M,1).')

%  
%  *WARNING*: This function is undocumented as it may be altered
%  at any time in the future without warning.

% NNSUMR(X)
%   X - Matrix of column vectors: [C1 C2 ... CN].
% Returns sum of each column.
%
% SUMROW differs from SUM by leaving column vectors unchanged.
%
% EXAMPLE: x = rands(4,5)
%          y = nnsumr(x)
