The function "HoADesign.m" returns the coordinates of sampling points in the spherical design. The spherical desings (equal-weight spherical quadrature rules) are constructed especially for higher order Ambisonics. The number of points in the psherical designs are thus , where denotes a truncation degree of the Ambisonics. Cartesian and spherical coordinate systems are available; but note that elevation angles θ differ from MATLAB's notation. The vertical angles are measured from the z-axis; and thus .
MAT files containing the coordinates of the spherical designs are named as "xxx-yyyyy.mat", where "xxx" denotes the exactitude degree of each spherical design and "yyyyy" denotes the number of points in the spherical design.
