摘要：
We present a program for computing symmetric quadrature rules on triangles andtetrahedra.A set of rules are obtained by using this program.Quadrature rules up toorder 21 on triangles and up to order 14 on tetrahedra have been obtained which are usefulfor use in finite element computations.All rules presented here have positive weights withpoints lying within the integration domain.
