Iteratively Calculated Eigenvalues,btain the wave functions required in the procedure can improve the precision to . The numerical application that we present here is again based on the vibration frequencies of an inhomogeneous string as presented in Chap. .. To close the chapter, we propose a project which applies the method to the case of an exponential attractive potential.

Convergence of Spectral Approximations,alculation of the interpolation error and the determination of the set of functions that gives rise to the best interpolation in such methods. In last section, we present assignments in order to analyze the rate of convergence and the error of various sets of basis functions in an expansion.

Chebyshev Polynomials as Basis Functions,val with the smallest error for functions that do not have strong singularities. The convergence of the expansion of functions in terms of Chebyshev polynomials will be illustrated, as well as the accuracy of the calculation of integrals and of derivatives. A novel “hybrid” method for calculating derivatives of higher order will also be described.
