View source: R/midpt.R

Description

Use the rectangle method to integrate a function

Usage

1
midpt(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 midpt function uses the rectangle method 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 the rectangles. Additional options are passed to the function f when evaluating.

Value

the value of the integral
