:fortran_help: " SUBROUTINE SLASWP( N, A, LDA, K1, K2, IPIV, INCX )\n\n\
* Purpose\n\
* =======\n\
*\n\
* SLASWP performs a series of row interchanges on the matrix A.\n\
* One row interchange is initiated for each of rows K1 through K2 of A.\n\
*\n\n\
* Arguments\n\
* =========\n\
*\n\
* N (input) INTEGER\n\
* The number of columns of the matrix A.\n\
*\n\
* A (input/output) REAL array, dimension (LDA,N)\n\
* On entry, the matrix of column dimension N to which the row\n\
* interchanges will be applied.\n\
* On exit, the permuted matrix.\n\
*\n\
* LDA (input) INTEGER\n\
* The leading dimension of the array A.\n\
*\n\
* K1 (input) INTEGER\n\
* The first element of IPIV for which a row interchange will\n\
* be done.\n\
*\n\
* K2 (input) INTEGER\n\
* The last element of IPIV for which a row interchange will\n\
* be done.\n\
*\n\
* IPIV (input) INTEGER array, dimension (K2*abs(INCX))\n\
* The vector of pivot indices. Only the elements in positions\n\
* K1 through K2 of IPIV are accessed.\n\
* IPIV(K) = L implies rows K and L are to be interchanged.\n\
*\n\
* INCX (input) INTEGER\n\
* The increment between successive values of IPIV. If IPIV\n\
* is negative, the pivots are applied in reverse order.\n\
*\n\n\
* Further Details\n\
* ===============\n\
