(Rockafellar, Convex Analysis, Thm 25.5) a convex function is differentiable almost everywhere on the interior of its domain. In other words, if you pick x∈ domf uniformly at random, then with probability 1, f is differentiable at x. intuition. (in R.) Subgradients are closed convex sets, so in R subgradients are closed intervals.
