#include "lash-ndd.h"
ndd *ndd_difference(ndd *nd1, ndd *nd2);
This function computes an NDD representing the difference between the
sets represented by the two NDDs *nd1 and *nd2,
i.e., the set of all the vectors that belong to the set represented
by *nd1 and that do not belong to the set represented by
*nd2. The two operand NDDs must use the same base, the
same dimension, and operate in the same direction.
This function does not modify *nd1 or *nd2.
In the case of success, this function returns a pointer to a
newly created NDD. In the case of an error, it returns
a NULL pointer and sets
lash_errno.
