# A simple Method to approximate the Gradient.

No doubt, the **gradient **is a mathematical construct with many applications to real-world problems. Among others, it is the core tool for some **optimization techniques **like the ‘steepest descent’. But also, it can be used to **detect edges in images**, or to describe the **dynamics of a heat flow**.

In this short article I want to quickly show you a way to efficiently approximate the gradient for…
