huber implements the huber loss, defined as \(x^2\) when \( \left\lvert x\right\rvert \leq M \) and \( M( 2\left\lvert x\right\rvert -M)\) for \( \left\lvert x\right\rvert \geq M\)


y = huber(x,M)


The operator is implemented using a graph representation based on SOCP and can thus only be used in scenarios where YALMIP can propagate convexity and use a conic model.
