Non symmetric test problem

On November 15th, 1995 the "Laplace Symphony" symposium has been organised by the University of Groningen. The topic of the symposium was: to compare various direct and iterative methods to solve the discretized Laplace equation. A number of test problems has been defined. The results of this comparison is published in:

In this page we summarize the information of the non symmetric test problem.
