Oracle Solaris Studio Performance Library vcosti(3P) NAME vcosti - initialize the array WSAVE, which is used in VCOST. SYNOPSIS SUBROUTINE VCOSTI(N, WSAVE) INTEGER N REAL WSAVE(*) SUBROUTINE VCOSTI_64(N, WSAVE) INTEGER*8 N REAL WSAVE(*) F95 INTERFACE SUBROUTINE VCOSTI(N, WSAVE) INTEGER :: N REAL, DIMENSION(:) :: WSAVE SUBROUTINE VCOSTI_64(N, WSAVE) INTEGER(8) :: N REAL, DIMENSION(:) :: WSAVE C INTERFACE #include <sunperf.h> void vcosti(int n, float *wsave); void vcosti_64(long n, float *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 (2 * N + 15) or greater. VCOSTI is called once to initialize WSAVE before calling VCOST and need not be called again between calls to VCOST 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 vcosti(3P)
