Fast construction of the discrete Green operator for a second order ordinary differential equation
Jan Blechta, Vít Průša, Ladislav Trnka +1
We consider linear second order differential equation y''= f with zero Dirichlet boundary conditions. At the continuous level this problem is solvable using the Green function, and…
