odl.solvers.nonsmooth.proximal_operators.proximal_nonnegativity(space)[source]

Function to create the proximal operator of G(x) = ind(x >= 0).

Function for the proximal operator of the functional G(x)=ind(x >= 0) to be initialized.

Parameters:
spaceLinearSpace

Domain of the functional G(x)

Returns:
prox_factoryfunction

Factory for the proximal operator to be initialized
