Abstrakt

The software presents the implementation of novel projection lemma, that can be used in various applications of proximal optimization where the projection onto a box-type convex set is needed. Such a projection admits using an explicit formula instead of iterative computation, resulting in the reduction of the computational cost. In this package, the benefit of the new projector is demonstrated on an audio declipping task. Implementation is done in the MATLAB environment.
