Function/Subroutine Documentation
subroutine dlapmr (logicalFORWRD, integerM, integerN, double precision, dimension( ldx, * )X,
integerLDX, integer, dimension( * )K)
DLAPMR rearranges rows of a matrix as specified by a permutation vector.
Purpose:
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.
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 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.
