Symmetrically processed splitting integrators for enhanced Hamiltonian Monte Carlo sampling
S. Blanes, M. P. Calvo, F. Casas +1
We construct integrators to be used in Hamiltonian (or Hybrid) Monte Carlo sampling. The new integrators are easily implementable and, for a given computational budget, may deliver…

Computing the matrix sine and cosine simultaneously with a reduced number of products
Muaz Seydaoglu, Philipp Bader, Sergio Blanes +1
A new procedure is presented for computing the matrix cosine and sine simultaneously by means of Taylor polynomial approximations. These are factorized so as to reduce the number o…
