Oracle Solaris Studio Performance Library cdotc(3P) NAME cdotc - compute the dot product of two vectors conjg(x) and y. SYNOPSIS COMPLEX FUNCTION CDOTC(N, X, INCX, Y, INCY) COMPLEX X(*), Y(*) INTEGER N, INCX, INCY COMPLEX FUNCTION CDOTC_64(N, X, INCX, Y, INCY) COMPLEX X(*), Y(*) INTEGER*8 N, INCX, INCY F95 INTERFACE COMPLEX FUNCTION DOTC(N, X, INCX, Y, INCY) COMPLEX, DIMENSION(:) :: X, Y INTEGER :: N, INCX, INCY COMPLEX FUNCTION DOTC_64(N, X, INCX, Y, INCY) COMPLEX, DIMENSION(:) :: X, Y INTEGER(8) :: N, INCX, INCY C INTERFACE #include <sunperf.h> complex cdotc(int n, complex *x, int incx, complex *y, int incy); complex cdotc_64(long n, complex *x, long incx, complex *y, long incy); PURPOSE cdotc compute the dot product of conjg(x) and y where x and y are n- vectors. ARGUMENTS N (input) On entry, N specifies the number of elements in the vector. If N is not positive then the function returns the value 0.0. Unchanged on exit. X (input) of DIMENSION at least ( 1 + ( n - 1 )*abs( INCX ) ). On entry, the incremented array X must contain the vector x. Unchanged on exit. INCX (input) On entry, INCX specifies the increment for the elements of X. Unchanged on exit. Y (input) of DIMENSION at least ( 1 + ( n - 1 )*abs( INCY ) ). On entry, the incremented array Y must contain the vector y. Unchanged on exit. INCY (input) On entry, INCY specifies the increment for the elements of Y. Unchanged on exit. 7 Nov 2015 cdotc(3P)
