HPL_dlacpy(3)                HPL Library Functions               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); }
