NAME

SYNOPSIS

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

DESCRIPTION

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

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);
}
