generateSubCoords

% Computing the sub coordinates
 @author Mazurek/Bartalsky

 Get the P_ij points out of the subcoordinates
 abs(M(i,x)-M(i,x+1))*(j/(m+1))
 We will generate m-sub coordinates between the corresponding
 coordinates pair.
% generateSubCoords.m parameters

 * *Input:*  
 * _M_ ... parallel coordinates of a dataset
 * _m_ ... number of subCoordinates
 * *Ouput:*
 * _subCoords_ ... the computed sub Coords
