complex SuiteSparse_long Syntax:

    #include "umfpack.h"
    void *Numeric ;
    umfpack_zl_free_numeric (&Numeric) ;

Purpose:

    Deallocates the Numeric object and sets the Numeric handle to NULL.  This
    routine is the only valid way of destroying the Numeric object.

Arguments:

    void **Numeric ;	    Input argument, set to (void *) NULL on output.

	Numeric points to a valid Numeric object, computed by umfpack_*_numeric.
	No action is taken if Numeric is a (void *) NULL pointer.
