Advances in Numerical Linear Algebra Conference and James Hardy Wilkinson Centenary

This year marks the 100th anniversary of the birth of James Hardy Wilkinson, FRS. Wilkinson developed the theory and practice of backward error analysis for floating-point computation, and developed, analyzed, and implemented in software many algorithms in numerical linear algebra. … Continue reading
