ABSTRACT
The unitary orbit of an complex matrix A is the set consisting of matrices unitarily similar to A. In this note we offer an alternative proof for a recent result, due to Li, Poon and Sze, on the possible ranks of the difference of matrices taken from the unitary orbits of two given orthogonal projections.
Keywords:
Rank, Orthogonal Projection, Unitary Matrix, Unitary Orbit
