Write a Matlab M-file for Romberg Integration that generates an n x n matrix R containing approximations of the integral I = Sf(z)dr, computed according to the following rules. The first collum of R contains the approximations of I obtained by the com- posite trapezoidal rule. More precisely, the k-th component R(k,1) is the ap- proximation of I obtained by using 2k-1 subintervals of [a, b] and computed recursively. The k-th component of the j-th collum of R is computed by the formula R(k, j - 1) R(k 1, j - 1) R(k,j) = R(k, j - 1) + 4j-1-1 where k > j and 2 j and 2
