LAP

This repo contains MATLAB functions and scripts to run examples using the Linearize and Project (LAP) method.

Dependencies

The codes and super-resolution examples rely heavily on the FAIR toolbox. This toolbox is required in the MATLAB filepath to run any of the examples in this repo.

Codes using hybrid regularization ('HyBR') with LAP or block coordinate descent require the IRtools toolbox in the MATLAB filepath.
