Explicit:
Implicit:
- A finite difference scheme is said to be explicit when it
can be computed forward in time using quantities from previous time
steps
- We will associate explicit finite difference schemes with
causal digital filters
- In implicit finite-difference schemes, the output of the
time-update (
above) depends on itself, so a causal
recursive computation is not specified
- Implicit schemes are generally solved using
- Implicit schemes are typically used offline
(not in real time)
