In this paper, we present a quadrature formula on triangular domains based on a set of simplex points. This formula is defined via the constrained mock-Waldron least squares approximation. Numerical experiments validate the effectiveness of the proposed method.

通过插值回归方法在三角域上的求积公式



在本文中,我们提出了一个基于一组单纯形点的三角域的正交公式。此公式通过约束 mock-Waldron 最小二乘近似定义。数值实验验证了所提方法的有效性。
