function cXcYcZ = gtm_m2r(X, Y, Z)
% Converts from a mesh-matrix to vector representation
%
%		Returns a matrix in which each row corresponds to a point 
%		on the grid defined by the mesh-matrices X and Y. 
%		The enumeration of points goes from the top-left corner of 
%		the mesh to the bottom-right, columnwise.
%
% Synopsis:	cXcYcZ = gtm_m2r(X, Y, Z)
%		cXcYcZ = gtm_m2r(X, Y)
%		cXcYcZ = gtm_m2r(X)
%
% Arguments:	X, Y, Z -	mesh-matrices for x-, y- and z- coordinates 
%				respectively; M-by-N.
%
% Return:	cXcYcZ -	matrix of rows of tuples; (M*N)-by-k, where 
%				k is 1, 2 or 3
