We have also learned that the point-successive methods need not demand more computer memory than point-simultaneous methods, and that the seemingly inherent asymmetry of the point-successive methods can be overcome. Furthermore, the linear methods described in this section are [Pg.79]

While the first point was addressed directly in Protocol 7.1, we will address the other points successively in the next paragraphs. [Pg.101]

By applying Aitken s method to a linearly convergent sequence obtained from fixed point (successive substitution) iteration, we can accelerate the convergence to quadratie order. This procedure is known as the Steffenson s method, which leads to Steffenson s algorithm as follows. [Pg.642]

III.C.3) and the use of special sampling methods to gain the rapid-convergence advantage of point-successive iteration without inducing asymmetry (Section III.C.2). [Pg.109]

If the elements present in the soUd have an incomplete strongly localized shell, the spectra show special features. This is the case, for example, for the rare earths, and we shall discuss this point successively for the emission and for the absorption processes. [Pg.26]

There is an important disadvantage stemming from variable separation and use of the FFT, however. One is limited to the use of the point simultaneous procedure in the determination of the coefficients. That is, all of the coefficients must be computed in an iteration before they can be resubstituted back in the iterative equations. With the point successive method, the improved coefficient determined by one equation is substituted in the succeeding equation to render additional improvement. With the test data treated in this work, the point simultaneous procedure converged much more slowly than the point successive method. [Pg.327]

For this work, the spectrometer function s(x) was determined by the method outlined in Section II.G.3 of Chapter 2. In digitizing the data, a sample density was chosen to accommodate about 70 samples taken across the full width at half maximum of s(x). A 25-point cubic polynomial smoothing filter was used in the deconvolution procedure to control high-frequency noise. Instead of the convolution in Eq. (13), the point-successive modification described in Section III.C.2 of Chapter 3 was employed. In Eq. (24) of Chapter 3, we replaced k with the expression [Pg.105]
