NAME
       vdsinti	-  initialize  the  array  WSAVE,  which is used in subroutine
       VSINT.

SYNOPSIS
       SUBROUTINE VDSINTI(N, WSAVE)

       INTEGER N
       DOUBLE PRECISION WSAVE(*)

       SUBROUTINE VDSINTI_64(N, WSAVE)

       INTEGER*8 N
       DOUBLE PRECISION WSAVE(*)

   F95 INTERFACE
       SUBROUTINE VSINTI(N, WSAVE)

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

       SUBROUTINE VSINTI_64(N, WSAVE)

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

   C INTERFACE
       #include <sunperf.h>

       void vdsinti(int n, double *wsave);

       void vdsinti_64(long n, double *wsave);

ARGUMENTS
       N (input) Length of the sequence to be transformed.  N >= 0.

       WSAVE (input/output)
		 On entry, an array of dimension (2N + N/2 + 15)  or  greater.
		 VSINTI	 is  called  once  to  initialize WSAVE before calling
		 VSINT and need not be called again between calls to VSINT  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.
