I have a polynomial in c & d.  I wish to extract the coefficients of lets say 3rd order i.e c^3+c^2d+c d^2+d^3. 

The polynomials can be of 2,3,4.. variables.  

coeffs(14*c^4 + 84*c^3*d + 180*c^2*d^2 + 165*c*d^3 + 55*d^4 + 5*c^3 + 21*c^2*d + 28*c*d^2 + 12*d^3 + 2*c^2 + 5*c*d + 3*d^2 + c + d + 1, [c, d], 'l');
     14, 84, 180, 165, 55, 5, 21, 28, 12, 2, 5, 3, 1, 1, 1

l[1];
                                4
                               c 

l[2];
                               3  
                              c  d

l;
 4   3     2  2     3   4   3     2     2   3   2        2        
c , c  d, c  d , c d , d , c , d c , c d , d , c , d c, d , c, d,
