# Function/Subroutine Documentation

## subroutine zlaswp (integerN, complex*16, dimension( lda, * )A, integerLDA, integerK1, integerK2, integer, dimension( * )IPIV, integerINCX)

ZLASWP performs a series of row interchanges on a general rectangular matrix.
Purpose:
``` ZLASWP performs a series of row interchanges on the matrix A.
One row interchange is initiated for each of rows K1 through K2 of A.
```
Parameters:
N
```          N is INTEGER
The number of columns of the matrix A.
```
A
```          A is COMPLEX*16 array, dimension (LDA,N)
On entry, the matrix of column dimension N to which the row
interchanges will be applied.
On exit, the permuted matrix.
```
LDA
```          LDA is INTEGER
The leading dimension of the array A.
```
K1
```          K1 is INTEGER
The first element of IPIV for which a row interchange will
be done.
```
K2
```          K2 is INTEGER
The last element of IPIV for which a row interchange will
be done.
```
IPIV
```          IPIV is INTEGER array, dimension (K2*abs(INCX))
The vector of pivot indices.  Only the elements in positions
K1 through K2 of IPIV are accessed.
IPIV(K) = L implies rows K and L are to be interchanged.
```
INCX
```          INCX is INTEGER
The increment between successive values of IPIV.  If IPIV
is negative, the pivots are applied in reverse order.
