LogM

<code>LogM(X)</code> computes the matrix logarithm of a general matrix using Armardillo. The returned value is a complex matrix but converted into a real one.

Implements operations for Riemannian manifolds, e.g., geodesic distance, Riemannian metric, exponential and logarithm maps, etc. Also incorporates random object generator on the manifolds. See Dai, Lin, and Müller (2021) <doi:10.1111/biom.13385>.
