dsinti

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.
