NAME
       vcosti - initialize the array WSAVE, which is used in VCOST.

SYNOPSIS
       SUBROUTINE VCOSTI(N, WSAVE)

       INTEGER N
       REAL WSAVE(*)

       SUBROUTINE VCOSTI_64(N, WSAVE)

       INTEGER*8 N
       REAL WSAVE(*)

   F95 INTERFACE
       SUBROUTINE VCOSTI(N, WSAVE)

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

       SUBROUTINE VCOSTI_64(N, WSAVE)

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

   C INTERFACE
       #include <sunperf.h>

       void vcosti(int n, float *wsave);

       void vcosti_64(long n, float *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.
		 VCOSTI	 is  called  once  to  initialize WSAVE before calling
		 VCOST and need not be called again between calls to VCOST  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.
