Lax Friedrichs Flux Splitting
 

Can anyone tell me where I can get information about Lax Friedrich's flux splitting. I need to understand this before I can go ahead with the rest of the (first) ENO paper by Shu and Osher. More specifically I need to know how 'alpha' which is defined as the (max) derivative of f(u) w.r.t u, is computed.

R.J. LeVeque has some on-line notes which describe the method. This should help you with everything and more
:). He also has another small book which is definitely worth reading (ha...I sound like a salesman...)
