SLAPMR rearranges rows of a matrix as specified by a permutation vector.
Function/Subroutine Documentation
subroutine slapmr (logical forwrd, integer m, integer n, real, dimension( ldx, * ) x, integer ldx, integer, dimension( * ) k)
SLAPMR rearranges rows of a matrix as specified by a permutation vector.
Purpose:
SLAPMR 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 REAL 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.
