hey guys,
So I'm working on a matlab function that uses simpsons 1/3 rule to find an integral. This is what I have done so far, but I'm not 100% confident.. If anyone would be able to have a look at give me some tips that would be very much appreciated. function [ I ] = simpsons3( func,a,b,n ) %Finds estimate integral from a to b of function using simpson 1/3 rule % % INPUTS % % func = function % % a = lower limit % % b = upper limit % % n=number of segments used for integration % % OUTPUTS % % I = integral estimate h = (ba)/(n1); sumE = 0; for i = a+2*h:h:b2*h sumE = sumE + func(i); end sumO = 0; for i = a+h:h:bh sumO = sumO + func(i); end I = (h/3)*(func(a)+4*sumE+2*sumO+func(b));
