HPL_dlacpy(3)

NAME
HPL_dlacpy - B := A.

SYNOPSIS
#include "hpl.h"

void HPL_dlacpy( const int M, const int N, const double * A, const int LDA, double * B, const int LDB );

DESCRIPTION
HPL_dlacpy copies an array A into an array B.

ARGUMENTS

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.

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.

A       (local input)           const double *
    On entry, A points to an array of dimension (LDA,N).

LDA     (local input)           const int
    On entry, LDA specifies the leading dimension of the array A. LDA must be at least MAX(1,M).

B       (local output)          double *
    On entry, B points to an array of dimension (LDB,N). On exit, B is overwritten with A.

LDB     (local input)           const int
    On entry, LDB specifies the leading dimension of the array B. LDB must be at least MAX(1,M).

EXAMPLE
#include "hpl.h"

int main(int argc, char *argv[])
{
   double a[2*2], b[2*2];
   a[0] = 1.0; a[1] = 3.0; a[2] = 2.0; a[3] = 4.0;
   HPL_dlacpy( 2, 2, a, 2, b, 2 );
   printf(" [%f,%f]\n", b[0], b[2]);
   printf("b=[%f,%f]\n", b[1], b[3]);
   exit(0);
   return(0);
}
