# Description

**HPL_dlaswp06T**
swaps columns of U with rows of A at positions
indicated by LINDXA.
# Arguments

M (local input) const int
On entry, M specifies the number of rows of A that should be
swapped with columns of U. M must be at least zero.

N (local input) const int
On entry, N specifies the length of the rows of A that should
be swapped with columns of U. N must be at least zero.

A (local output) double *
On entry, A points to an array of dimension (LDA,N). On exit,
the rows of this array specified by LINDXA are replaced by
columns of U.

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

U (local input/output) double *
On entry, U points to an array of dimension (LDU,*). This
array contains the columns of U that are to be swapped with
rows of A.

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

LINDXA (local input) const int *
On entry, LINDXA is an array of dimension M that contains the
local row indexes of A that should be swapped with U.
