ndd_base_expand, ndd_base_reduce

Synopsis

#include "lash-ndd.h" ndd *ndd_base_expand(ndd *nd); ndd *ndd_base_reduce(ndd *nd);

The function ndd_base_expand computes an NDD representing the set { r^k x | x in S and k in N }, where S is the subset of Z represented by the NDD *nd. The function ndd_base_reduce computes an NDD representing the set { x / r^k | x in S and k in N }. For both functions, the NDD *nd is supposed to be of dimension 1 and to use the numeration base r.

Warning: The use of these functions is strongly discouraged, since they might no longer appear in future releases of the package.

These functions do not modify *nd.

Return values

In the case of success, the functions return a pointer to a newly created NDD. In the case of an error, they return a NULL pointer and set lash_errno.

Diagnostics

LASH_ERR_NOT_INIT: The package has not been initialized.
LASH_ERR_DIMENSION: The dimension is not 1.
LASH_ERR_NO_MEM: Insufficient memory.
LASH_ERR_CORRUPT: Corrupt NDD.
