subroutine clapmt (logicalFORWRD, integerM, integerN, complex, dimension( ldx, * )X, integerLDX, integer, dimension( * )K)¶
CLAPMT performs a forward or backward permutation of the columns of a matrix. Purpose: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
Author:
FORWRD is LOGICAL = .TRUE., forward permutation = .FALSE., backward permutationM
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 (N) On entry, K contains the permutation vector. K is used as internal workspace, but reset to its original value on output.
