Solve after factorization

Python API

SolveAfterLDLPiv(A, dSub, p, B[, conjugate=True])
Parameters

  • A – The factored dense matrix

  • dSub – The vector containing the subdiagonal of \(D\)

  • p – The integer permutation vector

  • B – The right-hand sides to be solved against (in-place)

  • conjugate – (optional) If an \(LDL^H\) factorization was performed
