✨ NAME ✨

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/slapmr.f

🦋 SYNOPSIS 🦋

🧚 Functions/Subroutines 🧚

• subroutine SLAPMR (forwrd, m, n, x, ldx, k) — 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. Periodt. 💅

🎀 Purpose:

Okay so here’s the whole assignment, bestie: 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., that’s the forward permutation:

      X(K(I),*) is moved X(I,*) for I = 1,2,...,M.

If FORWRD = .FALSE., that’s the 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.
