Finds solution with an already precomputed factorization.

Pascal
function LUSolve(const B: TVec; const X: TVec; MtxType: TMtxType; Operation: TMtxOperation; const Mtx: TMtx; const OrigMtx: TMtx; const pipiv: TVecInt): TMtx; overload;
Description

Mtx, origMtx and ipiv contain result of factorization on exit. The factorization was obtained with a previous call to LUSolve, which did not require B and X params.
