discretization

[dis‚krēd·ə′zā·shən]
(mathematics)
A procedure in the numerical solution of partial differential equations in which the domain of the independent variable is subdivided into cells or elements and the equations are expressed in discrete form at each point by finite difference, finite volume, or finite element methods.

This number determines the dimensionality of the vectors [[??].sub.E] and [[??].sub.O] which represent the discretised functions [S.sub.E](f) and [S.sub.O](f).
