NAME
       dsinti  - initialize the array WSAVE, which is used in subroutine SINT.


SYNOPSIS
       SUBROUTINE DSINTI(N, WSAVE)

       INTEGER N
       DOUBLE PRECISION WSAVE(*)

       SUBROUTINE DSINTI_64(N, WSAVE)

       INTEGER*8 N
       DOUBLE PRECISION WSAVE(*)




   F95 INTERFACE
       SUBROUTINE SINTI(N, WSAVE)

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

       SUBROUTINE SINTI_64(N, WSAVE)

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




   C INTERFACE
       #include <sunperf.h>

       void dsinti(int n, double *wsave);

       void dsinti_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.
                 SINTI  is called once to initialize WSAVE before calling SINT
                 and need not be called again between calls to SINT 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.
