摘要: |
将边界上的函数展成小波级数,利用循环矩阵方法,从核函数边界上的值,得到离散的积分方程系数矩阵,求解未知的小波级数系数,从而得到边界积分方程近似解,文中计算了一个二维拉普拉斯方程的解。 |

Abstract: |
The functions on boundary are expanded into wavelet series,and the coefficient matrices are obtained from the values of kernal functions on the boundary using a circulant matrix method. The approximate solution of boundary integral equation is worked out by solving the unknown wavelet coefficients. An example of 2D Laplace equation is given. |
