Quadrature for High-Order Geometries
|

|
|
|

|
|
QuaHOG is a repository of MATLAB functions for producing quadrature rules over high-order (polynomial or rational parametric) trimmed/intersected geometries in 2D. We plan to add 3D support as well.

The methods listed in the paper are in the SPECTRAL_quads.m (for spectrally convergent quadrature over 2D regions bounded by rational curves) and SPECTRALPE_quads.m (same behavior as SPECTRAL_quads, but exact for polynomials up to a pre-specified degree)
