Selected Columns of the Density Matrix

This repository contains MATLAB code for the Selected Columns of the Density Matrix (SCDM) suite of algorithms and includes the routines necessary to use the SCDM method in conjunction with the Wannier90 software package. Algorithmic details may be found in the manuscript:
