intg: Integration

Description

This function calculates the integration of y with respect to x.

Usage

intg(y, x)

Arguments

x

a vector of real values, not necessarily sorted.

y

a vector of function values at x.

Details

(x,y)s are sorted according to ascending x values and then the integration is calculated as sum of the products of average of adjacent y values and the difference of adjacent x values.

Examples

x <- seq(0, 1,length=100)
y <- x^2
intg(y, x)
