Function/Subroutine Documentation

 

subroutine clapmr (logical FORWRD, integer M, integer N, complex, dimension( ldx, * ) X, integer LDX, integer, dimension( * ) K)

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

Purpose:

 CLAPMR 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 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.
