(Thus "piecewise linear" is actually defined to mean "piecewise affine".) If the domain of the function is compact, there needs to be a finite collection of such intervals if the domain is not compact, it may either be required to be finite or to be locally finite in the reals.Įxamples A continuous piecewise linear functionį ( x ) = : CS1 maint: url-status ( link) Definition Ī piecewise linear function is a function defined on a (possibly unbounded) interval of real numbers, such that there is a collection of intervals on each of which the function is an affine function. For example, let’s define a simple piecewise function. You can also set the value which will be true when no condition is true. In mathematics and statistics, a piecewise linear, PL or segmented function is a real-valued function of a real variable, whose graph is composed of straight-line segments. To define a piecewise function, you have to put the condition and its value inside the piecewise () function and then the second condition and its value, and so on. ![]() JSTOR ( March 2013) ( Learn how and when to remove this template message).Unsourced material may be challenged and removed.įind sources: "Piecewise linear function" – news Please help improve this article by adding citations to reliable sources.
