simp38: Simpson's 3/8 rule

In cmna: Computational Methods for Numerical Analysis

Description

Use Simpson's 3/8 rule to integrate a function

Usage

simp38(f, a, b, m = 100)

Arguments

f	function to integrate
a	the a-bound of integration
b	the b-bound of integration
m	the number of subintervals to calculate

Details

The simp38 function uses Simpson's 3/8 rule to calculate the integral of the function f over the interval from a to b. The parameter m sets the number of intervals to use when evaluating. Additional options are passed to the function f when evaluating.

Value

the value of the integral
