* Purpose |
|
* ======= |
|
* |
|
* ZLAPMT 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. |
|
* |
|
* Arguments |
|
* ========= |
|
* |
|
* FORWRD (input) LOGICAL |
|
* = .TRUE., forward permutation |
|
* = .FALSE., backward permutation |
|
* |
|
* M (input) INTEGER |
|
* The number of rows of the matrix X. M >= 0. |
|
* |
|
* N (input) INTEGER |
|
* The number of columns of the matrix X. N >= 0. |
|
* |
|
* X (input/output) COMPLEX*16 array, dimension (LDX,N) |
|
* On entry, the M by N matrix X. |
|
* On exit, X contains the permuted matrix X. |
|
* |
|
* LDX (input) INTEGER |
|
* The leading dimension of the array X, LDX >= MAX(1,M). |
|
* |
|
* K (input/output) 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. |
