CBSfunc {CBSr}

CBSfunc

Description

Calculate either the Area Under the Curve (AUC) of a CBS function, or calculate the y coordinates of CBS function given x.

Usage

CBSfunc(xpos, ypos, x = NULL)

Arguments

xpos

Vector of real numbers of length 1+3n (n = 1, 2, 3, ...), corresponding to Bezier points' x-coordinates of a CBS function

ypos

Vector of real numbers of length 1+3n (n = 1, 2, 3, ...), corresponding to Bezier points' y-coordinates of a CBS function

x

Vector of real numbers, corresponding to x-coordinates of a CBS function. Default value is Null.

Value

If x is provided, return y coordinates corresponding to x. If x is not provided, return AUC.

Examples

CBSfunc(c(0,0.3,0.6,1),c(0.5, 0.2, 0.7, 0.9))
CBSfunc(c(0,0.3,0.6,1),c(0.5, 0.2, 0.7, 0.9),seq(0,1,0.1))
