HPL_dcopy(3) HPL Library Functions HPL_dcopy(3) NAME HPL_dcopy - y := x. SYNOPSIS #include "hpl.h" void HPL_dcopy( const int N, const double * X, const int INCX, double * Y, const int INCY ); DESCRIPTION HPL_dcopy copies the vector x into the vector y. ARGUMENTS N (local input) const int On entry, N specifies the length of the vectors x and y. N must be at least zero. X (local input) const double * On entry, X is an incremented array of dimension at least ( 1 + ( n - 1 ) * abs( INCX ) ) that contains the vector x. INCX (local input) const int On entry, INCX specifies the increment for the elements of X. INCX must not be zero. Y (local input/output) double * On entry, Y is an incremented array of dimension at least ( 1 + ( n - 1 ) * abs( INCY ) ) that contains the vector y. On exit, the entries of the incremented array Y are updated with the en- tries of the incremented array X. INCY (local input) const int On entry, INCY specifies the increment for the elements of Y. INCY must not be zero. EXAMPLE #include "hpl.h" int main(int argc, char *argv[]) { double x[3], y[3]; x[0] = 1.0; x[1] = 2.0; x[2] = 3.0; y[0] = 4.0; y[1] = 5.0; y[2] = 6.0; HPL_dcopy( 3, x, 1, y, 1 ); printf("y=[%f,%f,%f]\n", y[0], y[1], y[2]); exit(0); return(0); } SEE ALSO HPL_daxpy (3), HPL_dscal (3), HPL_dswap (3).
