NAME
       sinqi  -  initialize  the array xWSAVE, which is used in both SINQF and
       SINQB.


SYNOPSIS
       SUBROUTINE SINQI(N, WSAVE)

       INTEGER N
       REAL WSAVE(*)

       SUBROUTINE SINQI_64(N, WSAVE)

       INTEGER*8 N
       REAL WSAVE(*)




   F95 INTERFACE
       SUBROUTINE SINQI(N, WSAVE)

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

       SUBROUTINE SINQI_64(N, WSAVE)

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




   C INTERFACE
       #include <sunperf.h>

       void sinqi(int n, float *wsave);

       void sinqi_64(long n, float *wsave);



ARGUMENTS
       N (input) Length of the sequence to be transformed.  The method is most
                 efficient when N is a product of small primes.


       WSAVE (input/output)
                 On  entry,  an  array  of  dimension (3 * N + 15) or greater.
                 SINQI needs to be called only once to initialize WSAVE before
                 calling  SINQF  and/or  SINQB if N and WSAVE remain unchanged
                 between these calls.  Thus, subsequent transforms or  inverse
                 transforms of same size can be obtained faster than the first
                 since they do not require initialization of the workspace.
