The main function is coefficientslist.m and the script pat.m shows how to use it.
coefficientslist.m returns a list of pixels (coordinates x (row) and y (column)), with the angles of the tangents at them (a), and the magnitudes of the tangents (m). The angles are computed via filtering with morlet wavelets.
