Grassmannian Codebook using modified LBG algorithm

The code outputs the Grassmannian codebook using LBG algorithm modified using the chordal distance and the respective calculated centroid.

A Grassmannian codebook is a set of isotropically distributed points on the Grassmannian manifold G(k,d) such as area of a circle, surface of a sphere, etc.

The code provides the Grassmannian codebook using LBG algorithm modified using the chordal distance and the respectively computed centroid.
