6. Composite Simpson's Rule (Matlab) (6 points) (a) Create a Matlab function simpson38 in a file simpsons8.m that uses the composite Simpson's 3/8 rule to evaluate the integral of a function f over an interval (a, b). Parameters of simpsons8 are a handle to the function f, the interval boundaries a,b and the number of subintervals N (b) Use the function simpson38 to evaluate the elliptical integral E(0.5) from question 4 with N 8, 16, 32,64, 128
