A scalar, upper bound for the diameter of the convex hull of the
point set. For multi-domain spaces (e.g. fm_tensor() and
fm_collect()), a vector of upper bounds for each domain is returned.
A point set as an \(n\times d\) matrix, or an
fm_mesh_2d/1d/sf related object.
Additional parameters passed on to the submethods.
Character string specifying the manifold type. Default for
matrix input is to treat the point set with Euclidean
\(\mathbb{R}^d\) metrics.
Use manifold="S2" for great circle distances on a sphere centred at the
origin.
