Matrix majorization in large samples

Muhammad Usman Farooq, Tobias Fritz, Erkka Haapasalo +1

One tuple of probability vectors is more informative than another tuple when there exists a single stochastic matrix transforming the probability vectors of the first tuple into th…

A new Lanczos type algorithm for system of linear equations

Muhammad Farooq, Abdellah Salhi

Lanczos-type algorithms are efficient and easy to implement. Unfortunately they breakdown frequently and well before convergence has been achieved. These algorithms are typically b…

A Switching Approach to Avoid Breakdown in Lanczos-type Algorithms

Muhammad Farooq, Abdellah Salhi

Lanczos-type algorithms are well known for their inherent instability. They typically breakdown when relevant orthogonal polynomials do not exist. Current approaches to avoiding br…

An alternative derivation of a new Lanczos-type algorithm for systems of linear equations

Saif Ullah, Muhammad Farooq, Abdellah Salhi

Various recurrence relations between formal orthogonal polynomials can be used to derive Lanczos-type algorithms. In this paper, we consider recurrence relation for the ch…

New Recurrence Relationships between Orthogonal Polynomials which Lead to New Lanczos-type Algorithms

Muhammad Farooq, Abdellah Salhi

Lanczos methods for solving consist in constructing a sequence of vectors such that $\textbf{r}_{k}=\textbf{b}-\textit{A…
