Abstrakt: In many practical problems, it is sometimes necessary to evaluate the derivative of function whose values are given approximately. In this paper, we consider the problem of estimating the derivative of a function observed with error. We present a proper regularization strategy and explain how to choose regularization parameter. In the end some numerical examples will further illustrate that this method is reasonable, effective and reasonable. [ABSTRACT FROM PUBLISHER]
