一个关于RBF的神经网络算法

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

[r, c] = size(v);

if r ~= 1
  error('dupRow: input vector must be row')
end

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