The following topics are covered: * least-squares approximation and regularization methods * interpolation by algebraic and trigonometric polynomials * basic results on best approximations * Euclidean approximation * Chebyshev approximation * asymptotic concepts: error estimates and convergence rates * signal approximation by Fourier and wavelet methods * kernel-based multivariate approximation * approximation methods in computerized tomography Providing numerous supporting examples, graphical illustrations, and carefully selected exercises,this textbook is suitable for introductory courses, seminars, and distance learning programs on approximation for undergraduate students HTTP:URL=https://doi.org/10.1007/978-3-030-05228-7
