Methods of numerical approximation

Аннотация

THE subject of this book is the approximation of functions of one or more variables by means of more elementary functions, regarded as a tool in numerical computation. This is not to say that we present the reader with rules of thumb so that he can programme for his computer without further thought, for none of us would claim to be able to predict the best method to apply to any particular problem. On the other hand we have been somewhat selective in discarding material of purely theoretical interest while retaining everything that seems practically relevant.
