Acclaimed actor Lisa Lu, whose storied career spans over 65 years across film, television and stage, will be honored with the 2,811th star on the Hollywood Walk of Fame. Bestowed the title of a ...

Standard computer implementations of Dantzig's simplex method for linear programming are based upon forming the inverse of the basic matrix and updating the inverse ...

Hello! I would like to know how to debug this error: "[ERROR PSM-0010] LU factorization of the G Matrix failed. SparseLU solver message: THE MATRIX IS STRUCTURALLY SINGULAR ... ZERO COLUMN AT" I have ...

Oklahoma City has had its fair share of success stories over the years. From the development of top draft picks, to undrafted free agents, trade acquisitions, second round picks, and everything in ...

ABSTRACT: The current paper is mainly devoted to construct a generalized symbolic Thomas algorithm that will never fail. Two new efficient and reliable computational algorithms are given. The ...

Sparse matrixes of the kind I am working with come from the finite element assembly, and are approaching 1M x 1M, so dense methods are just not feasible. I'm also pushing the limits of the single ...

Energy decomposition analysis (EDA) is an important class of methods to explore the nature of interaction between fragments in a chemical system. It can decompose the interaction energy into different ...

We introduce a new parallel algorithm for solving sparse LU factorization of planar matrices, which commonly arise in the finite element method for 2D PDEs. Existing scalable methods, such as the ...
