| 摘 要： | 在增维精细积分法的基础上,对矩阵进行分块计算.考虑非齐次项的特点,减小了矩阵的维数,实现简化计算,提高了计算效率,同时算法仍然具有增维精细积分法的原有优点.数值算例表明本方法在保持精度的同时提高了计算效率,在处理大型问题时将有着很大的优势.

| Abstract: | On the base of dimensional increment precise integration method,the block-matrix was computed.The method in the paper was further improved to reduce the dimensions of the matrix and realize the simplified computation when considering the characteristics of non-homogeneous items.Meanwhile,it can keep the existing merits of dimensional increment precise integration method.Numerical examples show that the method presented can maintain accuracy of the calculation and improve the calculation efficiency.So it wil... |
