Can anyone gives me the details description of two level finite difference approximation method?

02 February 2015 1 4K Report

I am not sure if you mean only the use of second and higher differences in numerical approximations, but some older texts have very thorough expositions.

three are: Mathematical Physics Jeffreys and Jeffreys Chapter 9 CUP 1956

Methods of Mathematical Computation Herriot, Wiley 1963

Modern Computing Methods UK National Physical Lab Philos Library NY 1961
