parametrický

Parametrický is an adjective used in Czech and related languages to denote something that depends on one or more parameters, or that is described using parameters. In mathematics and related fields, a parametric representation expresses a quantity as a function of a parameter, rather than as an explicit function of another variable.

In mathematics, a parametric curve or surface is described by equations in terms of one or more parameters. For a two-dimensional curve, this takes the form x = f(t), y = g(t) for t in some interval. Parametric forms can describe shapes that are difficult to capture with explicit x = f(y) or y = f(x) equations alone. They allow flexible modeling of motion, trajectories, and irregular geometries, and they underpin many numerical methods and animations.

In statistics, parametric methods assume that data arise from a distribution belonging to a fixed family characterized by a finite set of parameters (for example, a normal distribution with mean μ and standard deviation σ). Parametric approaches contrast with nonparametric or distribution-free methods, which make fewer assumptions about the underlying form of the data.

In design, computer graphics, and computer-aided engineering, parametric modeling uses parameters to define geometry and features. Adjusting a parameter propagates changes through dependent elements, enabling efficient design exploration and constraint-based modeling.

Etymology-wise, parametrický is derived from parameter and the Czech suffix -ický, mirroring the English term parametric. It appears in technical and scientific contexts to indicate dependence on adjustable quantities. See also parametric equation, parametric distribution, and parametric design.
