Recode the Romberg procedure so that all the trapezoid rule results are computed first and stored in the first column. Then in a separate procedure,
procedures Extrapolate(n, (ri ))
carry out Richardson extrapolation, and store the results in the lower triangular part of the (ri ) array. What are the advantages and disadvantages of this procedure over the routine given in the text? Test on the two integrals
using only one computer run.
