central_derivative R Documentation
Estimate the value of a derivative on an irregular grid using the
central difference method
Description
Estimate the value of the derivative of a function based on
three irregularly-spaced points. The method is based on a second-order
Taylor expansion of the function around x1.
Usage
central_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 derivative at x1.
