check_interpolconcave: check_interpolconcave

In andrea2910/ars: Adaptive Rejection Sampling

Description

given a (sorted) set of points, check if the interpolating function is concave he function will loop through all points in x and calculate the interpolated value

Usage

check_interpolconcave(x, f)

Arguments

x	x points
f	represent f(x)

Value

a boolean TRUE or FALSE. A TRUE means the function is concave

Examples

log_f <- function(x) log(dnorm(x))
x <- seq(-3, 3, by=1)
y <- log_f(x)
