function b = nncpy(m,n)
%NNCPY Make copies of a matrix.
%	
%	*WARNING*: This function is undocumented as it may be altered
%	at any time in the future without warning.

%	NNCPY copies matrices directly as appossed to interleaving
%   the copies as done by COPYINT.
%
% NNCPY(M,N)
%   M - Matrix.
%   N - Number of copies to make.
% Returns:
%   Matrix = [M M ...] where M appears N times.
%
% EXAMPLE: M = [1 2; 3 4; 5 6];
%          n = 3;
%          X = nncpy(M,n)
