The Midpoint Rule Assume that f(x) is continuous on [a, b]. Let n be a positive integer and Δx = b − a n. If [a, b] is divided into n subintervals, each of length Δx, and mi is the midpoint of the ith subinterval, set Mn = n ∑ i = 1f(mi)Δx.

Webb29 okt. 2012 · 4 Answers Sorted by: 1 Your interval [a,b] should be split into n intervals. This results in n+1 values for x that form the boundary of each partition. Your vector x contains only n elements. It appears that your code is only dealing with n terms instead of n+1 as required.
