NAME

     vsinti - initialize the array WSAVE, which is used  in  sub-
     routine 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)
               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.
