Subdifferential
Sign in to saveAlso known as subgradient
right|thumb|A convex function (blue) and "subtangent lines" at x_0 (red). In mathematics, the subderivative (or subgradient) generalizes the derivative to convex functions which are not necessarily differentiable. The set of subderivatives at a point is called the subdifferential at that point. Subderivatives arise in convex analysis, the study of convex functions, often in connection to convex optimization.

Das Subdifferential ist eine Verallgemeinerung des Gradienten auf nicht differenzierbare konvexe Funktionen. Das Subdifferential spielt eine wichtige Rolle in der konvexen Analysis sowie der konvexen Optimierung.
