function B = yvector(y)
% PURPOSE: repeats an nx1 vector y n times to form
%          an n*n x 1 vector
% --------------------------------------------------
% USAGE: B = yvector(y)
% where: y = an nx1 vector
% --------------------------------------------------
% RETURNS: B = [y
%               y
%               .
%               y], where there are n of them
