sinti

NAME

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

SYNOPSIS

  SUBROUTINE SINTI( N, WSAVE)
  INTEGER N
  REAL WSAVE(*)
 
  SUBROUTINE SINTI_64( N, WSAVE)
  INTEGER*8 N
  REAL WSAVE(*)

F95 INTERFACE

  SUBROUTINE SINTI( N, WSAVE)
  INTEGER :: N
  REAL, DIMENSION(:) :: WSAVE
 
  SUBROUTINE SINTI_64( N, WSAVE)
  INTEGER(8) :: N
  REAL, DIMENSION(:) :: WSAVE

C INTERFACE

#include <sunperf.h>

void sinti(int n, float *wsave);

void sinti_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. 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.
