Oracle Solaris Studio Performance Library vdsinqi(3P) NAME vdsinqi - initialize the array WSAVE, which is used in both VSINQF and VSINQB. SYNOPSIS SUBROUTINE VDSINQI(N, WSAVE) INTEGER N DOUBLE PRECISION WSAVE(*) SUBROUTINE VDSINQI_64(N, WSAVE) INTEGER*8 N DOUBLE PRECISION WSAVE(*) F95 INTERFACE SUBROUTINE VSINQI(N, WSAVE) INTEGER :: N REAL(8), DIMENSION(:) :: WSAVE SUBROUTINE VSINQI_64(N, WSAVE) INTEGER(8) :: N REAL(8), DIMENSION(:) :: WSAVE C INTERFACE #include <sunperf.h> void vdsinqi(int n, double *wsave); void vdsinqi_64(long n, double *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 with a dimension of at least (2 * N + 15). The same work array can be used for both VSINQF and VSINQB as long as N remains unchanged. Different WSAVE arrays are required for different values of N. This initialization does not have to be repeated between calls to VSINQF or VSINQB as long as N and WSAVE remain unchanged, thus subsequent trans- forms can be obtained faster than the first. 7 Nov 2015 vdsinqi(3P)
