Method of fundamental solutions based on geodesic distance for inhomogeneous heat conduction equations In anisotropic medium(用测地距离的基本解方法求解非齐次各向异性热传导方程)
近年来，径向基函数类方法数值求解偏微分方程问题越来越受欢迎.借此提出了一种求解非齐次各向异性热传导方程的基于测地距离的基本解方法，该方法属于径向基函数类方法，它无需进行变量变换，也无需计算奇异积分.用截断奇异值分解（TSVD）求解病态线性方程组.后面的数值例子将验证这种方法的稳定性和有效性....
