Simultaneous Approximation of Measurement Values and Derivative Data using Discrete Orthogonal Polynomials
Roland Ritt, Matthew Harker, Paul O'Leary
This paper presents a novel method for polynomial approximation (Hermite approximation) using the fusion of value and derivative information. Therefore, the least-squares error in…

Regularized Reconstruction of a Surface from its Measured Gradient Field
Matthew Harker, Paul O'Leary
This paper presents several new algorithms for the regularized reconstruction of a surface from its measured gradient field. By taking a matrix-algebraic approach, we establish gen…

A Matrix Framework for the Solution of ODEs: Initial-, Boundary-, and Inner-Value Problems
Matthew Harker, Paul O'Leary
A matrix framework is presented for the solution of ODEs, including initial-, boundary and inner-value problems. The framework enables the solution of the ODEs for arbitrary nodes.…
