Purpose:
``` 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.```
Parameters:
 [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.```
