quadrature rule The integral f(r)dr can be approximated by the basic a R(f) - 8-aj(+3)+8=f(a+38) = 2 4 2 4 (1) Write down the corresponding composite rule R(f; Ph) with uniform partition Ph to approximate f(x)dr. (2) Create a Matlab m-function named compquadrule.m to implement the composite rule. The m-function should have the calling syntax function R compquadrule (f, a, b, n) where f is the function handle to pass the integrand to the m-function, a and b are the lower and upper limits of the definite integral, and n is the number of subintervals in the uniform partition Ph.
