Abstract: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.
Keywords:multiresolution sampling  integral
