# Name

HPL_dlaswp03N copy rows of W into U.

# Synopsis

`#include "hpl.h"`
`void` `HPL_dlaswp03N(` `const int` `M`, `const int` `N`, `double *` `U`, `const int` `LDU`, `const double *` `W0`, `const double *` `W`, `const int` `LDW` `);`

# Description

HPL_dlaswp03N copies columns of W into rows of an array U. The destination in U of these columns contained in W is stored within W0.

# Arguments

    M       (local input)                 const int
            On entry, M  specifies  the  number  of columns of  W  stored
            contiguously that should be copied into U. M must be at least
            zero.

    N       (local input)                 const int
            On entry,  N  specifies  the  length of columns of  W  stored
            contiguously that should be copied into U. N must be at least
            zero.

    U       (local input/output)          double *
            On entry, U points to an array of dimension (LDU,N).  Columns
            of W are copied as rows within this array U at  the positions
            specified in W0.

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

    W0      (local input)                 const double *
            On entry,  W0  is an array of size (M-1)*LDW+1, that contains
            the destination offset  in U where the columns of W should be
            copied.

    W       (local input)                 const double *
            On entry, W  is an array of size (LDW,M),  that contains data
            to be copied into U. For i in [0..M),  entries W(:,i)  should
            be copied into the row or column W0(i*LDW) of U.

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