Piecewise linear may refer to:
*
Piecewise linear curve, a connected sequence of line segments
*
Piecewise linear function
In mathematics, a piecewise linear or segmented function is a real-valued function of a real variable, whose graph is composed of straight-line segments.
Definition
A piecewise linear function is a function defined on a (possibly unbounded) ...
, a function whose domain can be decomposed into pieces on which the function is linear
*
Piecewise linear manifold
In mathematics, a piecewise linear manifold (PL manifold) is a topological manifold together with a piecewise linear structure on it. Such a structure can be defined by means of an atlas, such that one can pass from chart to chart in it by piecewis ...
, a topological space formed by gluing together flat spaces
