```HPL_dlatcpy(3)               HPL Library Functions              HPL_dlatcpy(3)

NAME
HPL_dlatcpy - B := A^T

SYNOPSIS
#include "hpl.h"

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

DESCRIPTION
HPL_dlatcpy copies the transpose of an array A into an array B.

ARGUMENTS
M       (local input)           const int
On entry,  M specifies the number of  rows of the array B and
the number of columns of A. M must be at least zero.

N       (local input)           const int
On entry,  N specifies the number of  rows of the array A and
the number of columns of B. N must be at least zero.

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

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

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