Abstract

In many practical problems, it is sometimes necessary to evaluate the derivative of function whose values are given approximately. Firstly, the problem of estimating the derivative of a function observed with error is studied. It presents a proper regularization strategy and explain how to choose regularization parameter. Secondly, the regularization strategy above to the numerical differentiation is applied and discussed in the implementation of the numerical method and the tests which it has performed in order to investigate the accuracy and stability of the numerical differentiation procedure. Finally, some numerical examples will further illustrate that this method is reasonable, effective and reasonable.
