SYNOPSIS

   Functions/Subroutines

           ZLAPMR rearranges rows of a matrix as specified by a permutation vector.

Function/Subroutine Documentation

   subroutine zlapmr (logical FORWRD, integer M, integer N, complex*16, dimension( ldx, * ) X,
       integer LDX, integer, dimension( * ) K)
       ZLAPMR rearranges rows of a matrix as specified by a permutation vector.

       Purpose:

            ZLAPMR rearranges the rows of the M by N matrix X as specified
            by the permutation K(1),K(2),...,K(M) of the integers 1,...,M.
            If FORWRD = .TRUE.,  forward permutation:

                 X(K(I),*) is moved X(I,*) for I = 1,2,...,M.

            If FORWRD = .FALSE., backward permutation:

                 X(I,*) is moved to X(K(I),*) for I = 1,2,...,M.

       Parameters:
           FORWRD

                     FORWRD is LOGICAL
                     = .TRUE., forward permutation
                     = .FALSE., backward permutation

           M

                     M is INTEGER
                     The number of rows of the matrix X. M >= 0.

           N

                     N is INTEGER
                     The number of columns of the matrix X. N >= 0.

           X

                     X is COMPLEX*16 array, dimension (LDX,N)
                     On entry, the M by N matrix X.
                     On exit, X contains the permuted matrix X.

           LDX

                     LDX is INTEGER
                     The leading dimension of the array X, LDX >= MAX(1,M).

           K

                     K is INTEGER array, dimension (M)
                     On entry, K contains the permutation vector. K is used as
                     internal workspace, but reset to its original value on
                     output.
