Keywords

##### Usage
increment.fv(f, delta)
##### Arguments
f
Object of class "fv" representing a function.
delta
Numeric. The increase in the value of the function argument.
##### Details

This command computes the new function $$g(x) = f(x+h) - f(x-h)$$ where h = delta/2. The value of $g(x)$ is the change in the value of $f$ over an interval of length delta centred at $x$.

##### Value

• Another object of class "fv" compatible with X.
