==== Discrete modelling ====

In [[applied mathematics]], [[discrete modelling]] is the discrete analogue of [[continuous modelling]]. In discrete modelling, discrete formulae are fit to [[data]]. A common method in this form of modelling is to use [[recurrence relation]]. [[Discretization]] concerns the process of transferring continuous models and equations into discrete counterparts, often for the purposes of making calculations easier by using approximations. [[Numerical analysis]] provides an important example.
