Oracle Solaris Studio Performance Library dcosti(3P) NAME dcosti - initialize the array WSAVE, which is used in COST. SYNOPSIS SUBROUTINE DCOSTI(N, WSAVE) INTEGER N DOUBLE PRECISION WSAVE(*) SUBROUTINE DCOSTI_64(N, WSAVE) INTEGER*8 N DOUBLE PRECISION WSAVE(*) F95 INTERFACE SUBROUTINE COSTI(N, WSAVE) INTEGER :: N REAL(8), DIMENSION(:) :: WSAVE SUBROUTINE COSTI_64(N, WSAVE) INTEGER(8) :: N REAL(8), DIMENSION(:) :: WSAVE C INTERFACE #include <sunperf.h> void dcosti(int n, double *wsave); void dcosti_64(long n, double *wsave); ARGUMENTS N (input) Length of the sequence to be transformed. The method is most efficient when N - 1 is a product of small primes. N >= 2. WSAVE (input/output) On entry, an array of dimension (3 * N + 15) or greater. DCOSTI is called once to initialize WSAVE before calling DCOST and need not be called again between calls to DCOST 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. 7 Nov 2015 dcosti(3P)
