This book summarizes the basic theory of wavelets and some related
algorithms in an easy-to-understand language from the perspective of an
engineer rather than a mathematician. In this book, the wavelet solution
schemes are systematically established and introduced for solving
general linear and nonlinear initial boundary value problems in
engineering, including the technique of boundary extension in
approximating interval-bounded functions, the calculation method for
various connection coefficients, the single-point Gaussian integration
method in calculating the coefficients of wavelet expansions and unique
treatments on nonlinear terms in differential equations. At the same
time, this book is supplemented by a large number of numerical examples
to specifically explain procedures and characteristics of the method, as
well as detailed treatments for specific problems. Different from most
of the current monographs focusing on the basic theory of wavelets, it
focuses on the use of wavelet-based numerical methods developed by the
author over the years. Even for the necessary basic theory of wavelet in
engineering applications, this book is based on the author's own
understanding in plain language, instead of a relatively difficult
professional mathematical description. This book is very suitable for
students, researchers and technical personnel who only want to need the
minimal knowledge of wavelet method to solve specific problems in
engineering.
