| Abstract: | A vector quadrature method proposed by H.E.Hinnant is discussed. The numerical precision and stability of this method are studied. Two theorems are given and proved. A more efficient and numerically stable technique to form the vector integrals is presented and is compared with the block Gaussian quadrature method in computational complexity. |
