用Tikhonov正则化方法求一阶和两阶的数值微分 总被引:5,自引:0,他引:5
Numerical differentiation is an ill-posed problem, which is important in scientific research and practical applications.In this paper, we use the Tikhonov regularization method to discuss the first and secord order derivatives of a smooth function. The error estimate is also given. And the numerical results prove that our method is applicable. 相似文献
