fastTrapz: Calculate integral via trapezoid integration

In functionaldata/tDENS: Functional Data Analysis for Density Functions by Transformation to a Hilbert Space

Description

Calculate the value of an integra via trapezoid integration

Usage

fastTrapz(x, y)

Arguments

x	A vector of time-points 'x'; has to be sorted.
y	A vector of values at time f(x)

Value

A scalar with the associated value

Examples

n <- 1001
x <- seq(0, 3*pi, len = n)
y <- sin(x)
fastTrapz(x, y) # 1.999985
