java.lang.Object | +----org.netlib.lapack.DLAPMT
DLAPMT is a simplified interface to the JLAPACK routine dlapmt. This interface converts Java-style 2D row-major arrays into the 1D column-major linearized arrays expected by the lower level JLAPACK routines. Using this interface also allows you to omit offset and leading dimension arguments. However, because of these conversions, these routines will be slower than the low level ones. Following is the description from the original Fortran source. Contact seymour@cs.utk.edu with any questions.* .. * * Purpose * ======= * * DLAPMT rearranges the columns of the M by N matrix X as specified * by the permutation K(1),K(2),...,K(N) of the integers 1,...,N. * If FORWRD = .TRUE., forward permutation: * * X(*,K(J)) is moved X(*,J) for J = 1,2,...,N. * * If FORWRD = .FALSE., backward permutation: * * X(*,J) is moved to X(*,K(J)) for J = 1,2,...,N. * * Arguments * ========= * * FORWRD (input) LOGICAL * = .TRUE., forward permutation * = .FALSE., backward permutation * * M (input) INTEGER * The number of rows of the matrix X. M >= 0. * * N (input) INTEGER * The number of columns of the matrix X. N >= 0. * * X (input/output) DOUBLE PRECISION array, dimension (LDX,N) * On entry, the M by N matrix X. * On exit, X contains the permuted matrix X. * * LDX (input) INTEGER * The leading dimension of the array X, LDX >= MAX(1,M). * * K (input) INTEGER array, dimension (N) * On entry, K contains the permutation vector. * * ===================================================================== * * ..
