Adjective
(mathematics) Equal to a sum of finitely many linear functions, each defined on a convex polytope: said of functions between vector spaces
(topology) Having a defining atlas such that there is a piecewise linear homeomorphism between any pair of intersecting atlas charts: said of manifolds
piecewise-linear
Alternative spelling of piecewise linear
piecewise-linear
Piecewise-linear approximation Software such as the PLECS interface to Simulink uses piecewise-linear approximation of the equations governing the elements of a circuit. Source: Internet
In more complex cases the circuit may be analyzed with specialized computer programs or estimation techniques such as the piecewise-linear model. Source: Internet
This simplifies finding a start value for the iterative method that is close to the square root, for which a polynomial or piecewise-linear approximation can be used. Source: Internet
