摘要
从多分辨分析思想出发 ,推导出一种计算数值积分的算法 ,通过加强迫函数改善其精度。利用张量扩张的原理 ,将其推广到计算多维数值积分。结果表明 ,它不但与传统的Simpson算法有较好的一致性 ,而且对于震荡积分也有较高的精度。
A new numerical integral algorithm is presented according to the idea of multiresolution sampling Its precision is improved by the forcing function It's easy to use in high dimensions integral by tensor extending method The results show that it is not only in good agreement with traditional Simpson algorithm but also more precise to appreciate the high vibrating integral.
