The AZ algorithm for least squares systems with a known incomplete generalized inverse
Vincent Coppe, Daan Huybrechs, Roel Matthysen +1
We introduce an algorithm for the least squares solution of a rectangular linear system , in which may be arbitrarily ill-conditioned. We assume that a complementary matr…

A family of orthogonal rational functions and other orthogonal systems with a skew-Hermitian differentiation matrix
Arieh Iserles, Marcus Webb
In this paper we explore orthogonal systems in which give rise to a skew-Hermitian, tridiagonal differentiation matrix. Surprisingly, allowing the differ…

Fast Computation of Orthogonal Systems with a Skew-symmetric Differentiation Matrix
Arieh Iserles, Marcus Webb
Orthogonal systems in , once implemented in spectral methods, enjoy a number of important advantages if their differentiation matrix is skew-symmetric and…
