.SH DESCRIPTION

\fB\&HPL_dlacpy\fR

copies an array A into an array B.

.SH ARGUMENTS

.TP 8

M       (local input)           const int

On entry,  M specifies the number of rows of the arrays A and

B. M must be at least zero.

.TP 8

N       (local input)           const int

On entry,  N specifies  the number of columns of the arrays A

and B. N must be at least zero.

.TP 8

A       (local input)           const double *

On entry, A points to an array of dimension (LDA,N).

.TP 8

LDA     (local input)           const int

On entry, LDA specifies the leading dimension of the array A.

LDA must be at least MAX(1,M).

.TP 8

B       (local output)          double *

On entry, B points to an array of dimension (LDB,N). On exit,

B is overwritten with A.

.TP 8

LDB     (local input)           const int

On entry, LDB specifies the leading dimension of the array B.

LDB must be at least MAX(1,M).

.SH EXAMPLE

\fI\&#include "hpl.h"\fR

   a[0] = 1.0; a[1] = 3.0; a[2] = 2.0; a[3] = 4.0;

.br

   HPL_dlacpy( 2, 2, a, 2, b, 2 );

.br

   printf("  [%f,%f]\en", b[0], b[2]);

.br
