This is another formulation of a composite Simpson's rule: instead of applying Simpson's rule to disjoint segments of the integral to be approximated, Simpson's rule is applied to overlapping segments, yielding The formula above is obtained by combining the composite Simpson's 1/3 rule with the one consisting of using Simpson's 3/8 rule in the extreme subintervals and Simpson's 1/3 rule in the r… 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. EDIT:: Now you have modified the question based on the above, try this Webb25 mars 2024 · However, Simpson's 3/8 rule requires three subintervals per iteration, which means that it may be less efficient than Simpson's 1/3 rule for some applications. Additionally, some functions may require a large number of subintervals to achieve a desired level of accuracy, which can increase the computational cost of the method. greenville in house finances
