trapezoid: Trapezoidal Integration

In david850803/MC.makes.perfect: Monte Carlo integration

Description

The numerical integration of ftn from a to b,using the trapezoidal rule with n subdivisions.

Usage

trapezoid(ftn, a, b, n = 100)

Arguments

ftn	a function of single variable.
a	lower bound of the integration. Must be finite.
b	upper bound of the integration. Must be finite and assume b > a.
n	number of partitions.

Details

The integration calculates the trapezoid area of each subdivisions and sums them up.
