The stability radius of an object (system, function, matrix, parameter) at a given nominal point is the radius of the largest ball, centered at the nominal point, all of whose elements satisfy pre-determined stability conditions. The picture of this intuitive notion is this: where denotes the nominal point, denotes the space of all possible values of the object , and the shaded area, , represents the set of points that satisfy the stability conditions. == Abstract definition == The formal definition of this concept varies, depending on the application area. The following abstract definition is quite useful〔Zlobec S. (2009). Nondifferentiable optimization: Parametric programming. Pp. 2607-2615, in ''Encyclopedia of Optimization,'' Floudas C.A and Pardalos, P.M. editors, Springer.〕〔Sniedovich, M. (2010). A bird's view of info-gap decision theory.
