Category:Piecewise linear functions

This category is about functions f: XY whose domain X can be split into finitely many parts X = X1 ∪ ... ∪ Xn, such that f is linear on each part Xi.

As a special case (viz. n=1), this subsumes linear functions; therefore, the latter are a subcategory (rather than a supercategory) of piecewise linear functions.
