- These routines are part of the SCSL Scientific Library and can be loaded
- using either the -lscs or the -lscs_mp option. The -lscs_mp option
- directs the linker to use the multi-processor version of the library.
-
- When linking to SCSL with -lscs or -lscs_mp, the default integer size is
- 4 bytes (32 bits). Another version of SCSL is available in which integers
- are 8 bytes (64 bits). This version allows the user access to larger
- memory sizes and helps when porting legacy Cray codes. It can be loaded
- by using the -lscs_i8 option or the -lscs_i8_mp option. A program may use
- only one of the two versions; 4-byte integer and 8-byte integer library
- calls cannot be mixed.

- DLAPMT 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.

-
- 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) DOUBLE PRECISION 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) INTEGER array, dimension (N)
- On entry, K contains the permutation vector.
