Because of its suitability for parallel computation, the matrix sign function is a popular algorithm for solving the algebraic Riccati equation (ARE). The algorithm can be numerically unstable,â€¦ (More)

A parallel algorithm for solving the algebraic Riccati equation is described and its performance on an Intel iPSC/d5 is reported. Three variations of the matrix sign function algorithm are compared.â€¦ (More)

Code improvements have been made to the Surface Extraction from TIN based Search-space Minimization (SETSM) software, used to produce digital elevation maps from satellite imagery. The improvementsâ€¦ (More)
