Special attention is given to the question whether an analogue of the Reinsch algorithm is valid and criteria are given such that the associated matrix R is strictly diagonal dominant</p> </div> </div> </div>}, number={1}, journal={Proceedings of the Bulgarian Academy of Sciences}, author={Kounchev, Ognyan and Render, Hermann and Tsachev, Tsvetomir}, year={2022}, month={Feb.}, pages={11–18} }
