/* CHOLMOD Partition module, interface to CAMD, CCOLAMD, and CSYMAMD
*
* An interface to CCOLAMD and CSYMAMD, constrained minimum degree ordering
* methods which order a matrix following constraints determined via nested
* dissection.
*
* These functions do not require METIS. They are installed unless NCAMD
* is defined:
* cholmod_ccolamd interface to CCOLAMD ordering
* cholmod_csymamd interface to CSYMAMD ordering
* cholmod_camd interface to CAMD ordering
*
* Requires the Core and Cholesky modules, and two packages: CAMD,
* and CCOLAMD. Used by functions in the Partition Module.
