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.
