CLAPMT(3F) CLAPMT(3F)
CLAPMT - rearrange 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
SUBROUTINE CLAPMT( FORWRD, M, N, X, LDX, K )
LOGICAL FORWRD
INTEGER LDX, M, N
INTEGER K( * )
COMPLEX X( LDX, * )
CLAPMT 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.
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) COMPLEX 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.
