This paper presents that the closure function of convex func-tion in Hilbert space is definied by affine function approximation.On the ba-sis of closure function of convex function,closure function of nonconvex func-tion is introduced by concept of convex hull function.Some properties ofclosure function of convex function and nonconvex function are discussed.
