NAME

SYNOPSIS

9       #include "hpl.h"
10
11       void HPL_dcopy( const int N, const double * X, const int INCX, double *
12       Y, const int INCY );
13

DESCRIPTION

15       HPL_dcopy copies the vector x into the vector y.
16

ARGUMENTS

18       N       (local input)           const int
19               On entry, N specifies the length of the vectors  x  and   y.  N
20               must be at least zero.
21
22       X       (local input)           const double *
23               On entry,  X  is an incremented array of dimension  at  least (
24               1 + ( n - 1 ) * abs( INCX ) )  that  contains the vector x.
25
26       INCX    (local input)           const int
27               On entry, INCX specifies the increment for the elements  of  X.
28               INCX must not be zero.
29
30       Y       (local input/output)    double *
31               On entry,  Y  is an incremented array of dimension  at  least (
32               1 + ( n - 1 ) * abs( INCY ) )  that  contains the vector y.  On
33               exit, the entries of the incremented array  Y  are updated with
34               the entries of the incremented array X.
35
36       INCY    (local input)           const int
37               On entry, INCY specifies the increment for the elements  of  Y.
38               INCY must not be zero.

EXAMPLE

41       #include "hpl.h"
42
43       int main(int argc, char *argv[])
44       {
45          double x[3], y[3];
46          x[0] = 1.0; x[1] = 2.0; x[2] = 3.0;
47          y[0] = 4.0; y[1] = 5.0; y[2] = 6.0;
48          HPL_dcopy( 3, x, 1, y, 1 );
49          printf("y=[%f,%f,%f]\n", y[0], y[1], y[2]);
50          exit(0); return(0);
51       }
