simp: Simpson's rule

Description

Use Simpson's rule to integrate a function

Usage

simp(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

Value

the value of the integral

Details

The simp function uses Simpson's 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.

Examples

# NOT RUN {
f <- function(x) { sin(x)^2 + cos(x)^2 }
simp(f, -pi, pi, m = 10)
simp(f, -pi, pi, m = 100)
simp(f, -pi, pi, m = 1000)
