| Abstract: | In this aper, a kind of quadrature formulas are constructed by using the Euler Maclaurin summation formula. It has the same knotes as compound trapezoidal rule. But its convergence order is very high. It is especially suited to calculate the numerical integration with wavelets. |

| Keywords: | quadrature formula wavelet analysis convergence order |
