Integration of Functions of various orders with higher order sometimes but not always giving higher accuracy. Romberg integration which is discussed in 4.3 is a general formalism for making use of integration methods of a variety of different orders and we recommend it highly. Apart from the methods of this chapter and of Chapter 16 there are yet other methods for obtaining integrals. One important class is based on function approximation. We discuss explicitly the integration of functions by Chebyshev approximation Clenshaw-Curtis quadrature in 5.9. Although not explicitly discussed here you ought to be able to figure out how to do cubic spline quadrature using the output of the routine spline in 3.3. Hint Integrate equation 3.3.3 over x analytically. See 1 . Some integrals related to Fourier transforms can be calculated using the fast Fourier transform FFT algorithm. This is discussed in 13.9. Multidimensional integrals are another whole multidimensional bag of worms. Section 4.6 is an introductory discussion in this chapter the important technique of Monte-Carlo integration is treated in Chapter 7. CITED REFERENCES AND FURTHER READING Carnahan B.
