Bidiagonal Decompositions and Accurate Computations for the Ballot Table and the Fibonacci Matrix

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 1, February 2026.
ABSTRACT Riordan arrays include many important examples of matrices. Here we consider the ballot table and the Fibonacci matrix. For finite truncations of these Riordan arrays, we obtain bidiagonal decompositions. Using them, algorithms to solve key linear algebra problems for ballot tables and Fibonacci matrices with high relative accuracy are derived.

Definition and Computation of Tensor‐Based Generalized Function Composition

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 1, February 2026.
ABSTRACT Functions are fundamental to mathematics as they offer a structured and analytical framework to express relations between variables. While scalar and matrix‐based functions are well‐established, higher‐order tensor‐based functions have not been as extensively explored.

Supersaturated Designs for Main Effects and Two‐Factor Interactions

open access: yesQuality and Reliability Engineering International, Volume 42, Issue 1, Page 52-65, February 2026.
ABSTRACT Supersaturated designs (SSDs), which use fewer runs than factors, are employed in screening experiments to identify large main effects (MEs), even when the experimental setting may also involve factors that interact. This paper introduces new SSD design criteria that account for two‐factor interactions (2FIs) and compares them with designs ...
