23 mar 2012 · Simpson's 1/3 rule (with unit spacing). Simpson's 1/3 rule uses quadratic interpolants for numerical integration. To compute the integral for spacing different from one, multiply RES by the spacing increment. For vectors, SIMPSON(Y) is the integral of Y. For matrices, SIMPSON(Y) is a row vector with the integral over each column. For N-D
29 kwi 2011 · This function computes the integral "I" via Simpson's rule in the interval [a,b] with n+1 equally spaced points. Syntax: I = simpsons(f,a,b,n) Where, f= can either be an anonymous function (e.g. f=@(x) sin(x)) or a vector containing equally spaced values of the function to be integrated a= Initial point of interval b= Last point of interval
14 kwi 2016 · Here's the code for the composite Simpson's rule: function I = simpsons(f,a,b,n) if numel(f)>1 % If the input provided is a vector n=numel(f)-1; h=(b-a)/n; I= h/3*(f(1)+2*sum(f(3:2:end-2))+4*sum(f(2:2:end))+f(end)); else % If the input provided is an anonymous function h=(b-a)/n; xi=a:h:b; I= h/3*(f(xi(1))+2*sum(f(xi(3:2:end-2)))+4*sum(f(xi(2:2 ...
