# sigpy.prox.Conj¶

class sigpy.prox.Conj(prox)[source]

Returns the proximal operator for the convex conjugate function.

The proximal operator of the convex conjugate function $$g^*$$ is defined as:

$\text{prox}_{\alpha g^*} (x) = x - \alpha \text{prox}_{\frac{1}{\alpha} g} (\frac{1}{\alpha} x)$
