ZLAPMR rearranges rows of a matrix as specified by a permutation vector.
Download ZLAPMR + dependencies [TGZ] [ZIP] [TXT]ZLAPMR 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.
[in]  FORWRD  FORWRD is LOGICAL = .TRUE., forward permutation = .FALSE., backward permutation 
[in]  M  M is INTEGER The number of rows of the matrix X. M >= 0. 
[in]  N  N is INTEGER The number of columns of the matrix X. N >= 0. 
[in,out]  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. 
[in]  LDX  LDX is INTEGER The leading dimension of the array X, LDX >= MAX(1,M). 
[in,out]  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.
