Oracle Solaris Studio Performance Library dezfti(3P) NAME dezfti - initializes the array WSAVE, which is used in both DEZFTF and DEZFTB. SYNOPSIS SUBROUTINE DEZFTI(N, WSAVE) INTEGER N DOUBLE PRECISION WSAVE(*) SUBROUTINE DEZFTI_64(N, WSAVE) INTEGER*8 N DOUBLE PRECISION WSAVE(*) F95 INTERFACE SUBROUTINE DEZFTI(N, WSAVE) INTEGER :: N REAL(8), DIMENSION(:) :: WSAVE SUBROUTINE DEZFTI_64(N, WSAVE) INTEGER(8) :: N REAL(8), DIMENSION(:) :: WSAVE C INTERFACE #include <sunperf.h> void dezfti(int n, double *wsave); void dezfti_64(long n, double *wsave); ARGUMENTS N (input) Length of the sequence to be transformed. N >= 0. WSAVE (input/output) On entry, an array with a dimension of at least (3 * N + 15). The same work array can be used for both DEZFTF and DEZFTB 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 DEZFTF or DEZFTB as long as N and WSAVE remain unchanged, thus subsequent trans- forms can be obtained faster than the first. 7 Nov 2015 dezfti(3P)
