% The matrix StocF_1465 is obtained from a fluid-dynamical problem
% of flow in porous medium.  The computational grid consists of   
% tetrahedral Finite Elements discretizing an underground aquifer 
% with stochastic permeabilties.  Some further information may be 
% found in the following papers:
