what is the difference

what is the difference between semi discretization and full discretization??

how to make a differential equation to be semi discretized?

Re: what is the difference

Hi pococz;

Aren't those techniques usually used on PDE's. I only can do some discretization when the DE has initial conditions. I have heard of possibly using Galerkin's method but have long since forgotten it. Do you have a specific example where one was done without initial conditions?

Re: what is the difference

yes... i've heard some info about galerkin.. but,what is the difference? does the full discretization works more accurate than semi discretization? or the right moment to use one of them,when?

i agree.. discetization : when the DE has initial conditions
