Unlocbox - Proximal operators

The proximal operator of function f evaluated in z is the solution of the folowing equation:

\begin{equation*} prox_{f, \gamma }(z)=\min_z \frac{1}{2} \|x-z\|_2^2 + \gamma f(z) \end{equation*}

Here are a list of common usual proximal operators available in the UnLocBoX. We remember the reader that projections are particular cases of proximal operators.
