template<unsigned int dim>
struct comb< dim >
Position of the element of dimension d in the hyper-cube of dimension dim.
These objects are returned by the Hyper-cube static functions The number of non-zero d define the dimensionality of the object ( +1 or -1 its position in the hypercube)
Example
(0,1)
(-1,1) +---------+ (1,1)
| |
| |
(-1,0)| (0,0) | (1,0)
| |
| |
(-1,-1) +---------+ (1,-1)
(0,-1)
