zlapmt.f(3) LAPACK zlapmt.f(3)

zlapmt.f -


subroutine zlapmt (FORWRD, M, N, X, LDX, K)
 
ZLAPMT performs a forward or backward permutation of the columns of a matrix.

ZLAPMT performs a forward or backward permutation of the columns of a matrix.
Purpose:
 ZLAPMT 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.
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 (N)
          On entry, K contains the permutation vector. K is used as
          internal workspace, but reset to its original value on
          output.
