This is the git repository for the package polarzonoid on CRAN.
In each odd dimension is a convex body - the polar zonoid - whose generating functions are trigonometric polynomials. The polar zonoid is a straightforward generalization of the polar zonohedron in dimension 3, as defined by Chilton and Coxeter (1963). The package has some applications of the polar zonoid, including the properties of configuration spaces of arcs on the circle and 3x3 rotation matrices. There is also a root solver for trigonometric polynomials.
In other contexts, i.e. the theory of convex bodies, the term “polar zonoid” is short for “polar of a zonoid”, which is an entirely different concept.
