摘要

The problem of applying the projection-iteration method based on the simple iteration method to solving the numerical differentiation problem is investigated including the problem of finding a least admissible number of discrete time series elements for obtaining the time series derivative of the first order values with a given precision. The theorem of projection-iteration method convergence is formulated, the error estimate is obtained. The program simulating the numerical differentiation problem solution is worked out, the comparative analysis of the suggested method and a computational scheme of projection type is carried out for the example of differentiation problem solution of determined class of functions.
