I have tried, just for the fun of it, to write a MatLab-code for the composite Simpson's rule. As far as I can see, the code is correct, but my answers are not as accurate as I would like. If I try my code on the function f = cos(x) + e^(x^2), with a = 0, b = 1 and n = 7, my answer is roughly 1,9, when it should be 2,3.

Dec 28, 2020 · Simpson's rule is a Newton-Cotes formula for approximating the integral of a function using quadratic polynomials (i.e., parabolic arcs instead of the straight line segments used in the trapezoidal rule). Simpson's rule can be derived by integrating a third-order Lagrange interpolating polynomial fit to the function at three equally spaced points. In particular, let the function be tabulated at points , , and equally spaced by distance , and denote . Then Simpson's rule states that MATLAB Central contributions by Natalia Wong. ...

Simpson's 3/8 Rule. Simpson's 3/8 rule is similar to Simpson's 1/3 rule, the only difference being that, for the 3/8 rule, the interpolant is a cubic polynomial. Though the 3/8 rule uses one more function value, it is about twice as accurate as the 1/3 rule. Simpson's 3/8 rule states : Replacing (b-a)/3 as h, we get,5.2.1 Trapezoid Rule 5.2.2 Simpson’s Rule 5.2.3 Composite Newton–Cotes formulas. 5.2.4 Open Newton–Cotes Methods. 5.3 Romberg Integration . 5.4 Adaptive Quadrature . 5.5 Gaussian Quadrature.

Jun 23, 2013 · Simpson’s rule also corresponds to the 3-point Newton-Cotes quadrature rule. If the interval of integration [a, b] is in some sense “small”, then Simpson’s rule will provide an adequate approximation to the exact integral. By small, what we really mean is that the function being integrated is relatively smooth over the interval [a, b].
