单词	discretize
释义	discretize /dɪˈskriːtʌɪz / (also discretise) verb [with object] Mathematics Represent or approximate (a quantity or series) using a discrete quantity or quantities.To solve such equations we must retreat to discrete steps and computations, and sometimes the continuous space itself must be discretized over a mesh before submission to a computing device.... Ten categories appear to be sufficient for discretizing the integral over parameters. Approximations are made when the world is represented using continuous models (partial differential equations) and when these continuous models are discretized. Derivatives discretization /dɪskriːtʌɪˈzeɪʃ(ə)n/ noun ... Analyses all required a planar mathematical discretization of a region containing a prescribed number of cells with prescribed orientations. For example, engineers use multigrid methods to analyze numeric properties of physical phenomena using a hierarchy of grid discretization. To improve the accuracy of that extrapolation, we place a high premium on finding improved algorithms that reduce discretization artifacts.
