Computing the First Order Derivative with Backward DifferenceΒΆ

Causal Step

This step applies the Backward Difference method to approximate the first order derivative of a function or a time series. Note that step size(s) are known a priori for a time series.

Input Parameters

  1. A function or a time series
  2. Step size(s)

Output Parameters

  1. First derivative of a function or a time series
