An extended method of fundamental solutions for inverse boundary value problems associated with one-dimensional nonhomogenous heat conduction(广义基本解方法求解一维非齐次热传导方程的反边界值问题)

给出一种求解一维非齐次热传导方程反边界值问题的无网格方法,即广义基本解方法.该方法将问题的解分成特解和相应齐次问题的解两个部分:齐次解用基本解方法求解,而特解则是利用相应的特征方程的基本解近似得到.鉴于所考虑问题的不适定性,应用截断奇异值分解和L曲线准则求解离散后得到的高度病态的线性方程组.最后给出数值例子说明该方法的稳定性和有效性,并分析了数值解精度与各参数之间的关系....
