Finite-difference Sentence Examples
Even where u is an explicit function of x, so that f x udx may be expressed in terms of x, it is often more convenient, for construction of a table of values of such an integral, to use finite-difference formulae.
These are automatically computed by finite difference approximation (either forward or central differences ).
We use 2D finite-difference modeling methods to compute the propagation of seismic waves in simplified volcanic structures.
