This package provides p-adaptive quadrature for periodic integrands using the spectrally-convergent Periodic Trapezoidal Rule (PTR) Convergence to a user-specified tolerance is automated by the algorithm.
Additionally, symmetries can be used to reduce the number of distinct quadrature points needed for the integration, which in computational solid state physics is known as Monkhorst-Pack integration.
The algorithm of autosymptr
is based on the ones described in
