Recent results on Clarke Jacobians obtained by D. Bartl and M. Fabian are extended to Bouligand Jacobians. In particular, we prove that every non-empty compact connected set of matrices can be expressed as the Bouligand Jacobian at the origin of a suitable Lipschitzian mapping which is moreover either countably piecewise affine or C∞-smooth off the origin. Given proofs are simpler and different from the previous ones.
