% small script demonstrating the RB-approach for nonlinear examples
%
% A burgers equation with Lax-Friedrichs flux is used for solving
% a convection problem: Several parameters are variable and 
% demonstrate the applicability of the model reduction 
% technique of interpolating the explicit space operator.
