HPL_dcopy - Man Page

#include "hpl.h"
 void HPL_dcopy( const int N, const double * X, const int INCX, double * Y, const int INCY );

HPL_dcopy copies the vector x into the vector y.

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 entries 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.
