# Description

**HPL_dlaswp10N**performs a sequence of local column interchanges on a matrix A. One column interchange is initiated for columns 0 through N-1 of A.

# Arguments

M (local input) const int __arg0__

N (local input) const int On entry, M specifies the number of rows of the array A. M must be at least zero.

A (local input/output) double * On entry, N specifies the number of columns of the array A. N must be at least zero.

LDA (local input) const int On entry, A points to an array of dimension (LDA,N). This array contains the columns onto which the interchanges should be applied. On exit, A contains the permuted matrix.

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