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 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.


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);
       }
