left_derivative R Documentation
Estimate the value of the left-derivative on an irregular grid
using three points
Description
Estimate the value of the right-derivative of a function
based on three irregularly-spaced points. The method is based on a
second-order Taylor expansion of the function around x2.
Usage
left_derivative(x0, x1, x2, y0, y1, y2)
Arguments
x0
The left point of the grid.
x1
The central point of the grid.
x2
The right point if the grid.
y0
The value of the function at x0.
y1
The value of the function at x1.
y2
The value of the function at x2.
Value
The value of the left-derivative at x2.
