A small function for numerically integrating a function with simpsons rule
npm install simpsons-ruleA handy function for numerically integrating a function via simpson's rule. Here's an example:
var simpsons = require('simpsons-rule');
var F = function(x) {
return 2 * x;
};
var result = simpsons(F, 0, 1); // integrate from 0 to 1. Should be close to 0.5
// Or provide a step count
result = simpsons(F, 0, 1, 1000);
