SYNOPSIS
       SUBROUTINE VDCOSTI(N, WSAVE)

       INTEGER N
       DOUBLE PRECISION WSAVE(*)

       SUBROUTINE VDCOSTI_64(N, WSAVE)

       INTEGER*8 N
       DOUBLE PRECISION WSAVE(*)




   F95 INTERFACE
       SUBROUTINE VCOSTI(N, WSAVE)

       INTEGER :: N
       REAL(8), DIMENSION(:) :: WSAVE

       SUBROUTINE VCOSTI_64(N, WSAVE)

       INTEGER(8) :: N
       REAL(8), DIMENSION(:) :: WSAVE




   C INTERFACE
       #include <sunperf.h>

       void vdcosti(int n, double *wsave);

       void vdcosti_64(long n, double *wsave);



ARGUMENTS
       N (input) Length of the sequence to be transformed.  The method is most
                 efficient when N - 1 is a product of small primes.  N >= 2.


       WSAVE (input/output)
                 On entry, an array of dimension (2 *  N  +  15)  or  greater.
                 VDCOSTI  is  called  once  to initialize WSAVE before calling
                 VDCOST and need not be called again between calls  to  VDCOST
                 if N and WSAVE remain unchanged.  Thus, subsequent transforms
                 of same size can be obtained faster than the first since they
                 do not require initialization of the workspace.
