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); } SEE ALSO HPL_dlacpy (3).
