function M = dupCol(v, n)
%  M = dupCol(v, n)
%
%  Duplicates v, a column vector, n times. Returns the
%  result as matrix M with n columns, each one a copy of v.
%
%  Inputs
%
%    v    a column vector (m-by-1)
%    n    a positive integer
%
%  Output
%
%    M    a matrix (m-by-n) matrix

[r, c] = size(v);

if c ~= 1
  error('dupCol: input vector must be column')
end

M = v(:, ones(1, n));
