CLASWP performs a series of row interchanges on a general rectangular matrix.
Download CLASWP + dependencies [TGZ] [ZIP] [TXT]CLASWP performs a series of row interchanges on the matrix A. One row interchange is initiated for each of rows K1 through K2 of A.
[in]  N  N is INTEGER The number of columns of the matrix A. 
[in,out]  A  A is COMPLEX 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. 
[in]  LDA  LDA is INTEGER The leading dimension of the array A. 
[in]  K1  K1 is INTEGER The first element of IPIV for which a row interchange will be done. 
[in]  K2  K2 is INTEGER The last element of IPIV for which a row interchange will be done. 
[in]  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. 
[in]  INCX  INCX is INTEGER The increment between successive values of IPIV. If IPIV is negative, the pivots are applied in reverse order.
