Evaluation of two-parameter extrapolation efficiency for one class of spectral problems with integral operator on a half-axis

The computational experiments on the evoluation of two-parameter extrapolation efficiency at numerical solving of one class of spectral problems for integral operator on the half-axis are carried out. The computational scheme to realize this extrapolation is proposed. The motion along h- and R-levels is combined optimally in this type of extrapolation. Due to the application of extrapolation procedure the eigenvalue precision could be improved twice on the average and algorithm complexity decreased by 1-2 orders
