vdsinti(3P) Sun Performance Library vdsinti(3P)NAMEvdsinti - initialize the array WSAVE, which is used in subroutine
VSINT.
SYNOPSIS
SUBROUTINE VDSINTI(N, WSAVE)
INTEGER N
DOUBLE PRECISION WSAVE(*)
SUBROUTINE VDSINTI_64(N, WSAVE)
INTEGER*8 N
DOUBLE PRECISION WSAVE(*)
F95 INTERFACE
SUBROUTINE VSINTI(N, WSAVE)
INTEGER :: N
REAL(8), DIMENSION(:) :: WSAVE
SUBROUTINE VSINTI_64(N, WSAVE)
INTEGER(8) :: N
REAL(8), DIMENSION(:) :: WSAVE
C INTERFACE
#include <sunperf.h>
void vdsinti(int n, double *wsave);
void vdsinti_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.
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.
