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

SYNOPSIS
       SUBROUTINE VSINTI(N, WSAVE)

       INTEGER N
       REAL WSAVE(*)

       SUBROUTINE VSINTI_64(N, WSAVE)

       INTEGER*8 N
       REAL WSAVE(*)

   F95 INTERFACE
       SUBROUTINE VSINTI(N, WSAVE)

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

       SUBROUTINE VSINTI_64(N, WSAVE)

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

   C INTERFACE
       #include <sunperf.h>

       void vsinti(int n, float *wsave);

       void vsinti_64(long n, float *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.
