Class Dlaswp

java.lang.Object
  extended by org.netlib.lapack.Dlaswp

public class Dlaswp
extends java.lang.Object

Following is the description from the original
Fortran source.  For each array argument, the Java
version will include an integer offset parameter, so
the arguments may not match the description exactly.

* .. * * Purpose * ======= * * DLASWP performs a series of row interchanges on the matrix A. * One row interchange is initiated for each of rows K1 through K2 of A. * * Arguments * ========= * * N (input) INTEGER * The number of columns of the matrix A. * * A (input/output) DOUBLE PRECISION 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 (input) INTEGER * The leading dimension of the array A. * * K1 (input) INTEGER * The first element of IPIV for which a row interchange will * be done. * * K2 (input) INTEGER * The last element of IPIV for which a row interchange will * be done. * * IPIV (input) INTEGER array, dimension (M*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 (input) INTEGER * The increment between successive values of IPIV. If IPIV * is negative, the pivots are applied in reverse order. * * Further Details * =============== * * Modified by * R. C. Whaley, Computer Science Dept., Univ. of Tenn., Knoxville, USA * * ===================================================================== * * .. Local Scalars ..
