DLAPMR 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.

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 DOUBLE PRECISION 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.
