vsinti(3P) Sun Performance Library vsinti(3P)NAMEvsinti - initialize the array WSAVE, which is used in subroutine VSINT.
SYNOPSIS
SUBROUTINE VSINTI(N, WSAVE)
INTEGER N
REAL WSAVE(*)
SUBROUTINE VSINTI_64(N, WSAVE)
INTEGER*8 N
REAL WSAVE(*)
F95 INTERFACE
SUBROUTINE VSINTI(N, WSAVE)
INTEGER :: N
REAL, DIMENSION(:) :: WSAVE
SUBROUTINE VSINTI_64(N, WSAVE)
INTEGER(8) :: N
REAL, DIMENSION(:) :: WSAVE
C INTERFACE
#include <sunperf.h>
void vsinti(int n, float *wsave);
void vsinti_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.
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.
