## Description

The ```exFinder``` web application calculates and visualizes interactively the extreme values of multivariate functions: 



It is based mathematically on ```SymPy``` and ```NumPy``` and graphically on ```Jupyter Notebook```, ```Plotly``` and ```Voila```. It has step by step features, based on  finding and characterizing stationary points by using the gradient and the Hessian, e.g. [[Alt, 2002]](https://link.springer.com/book/10.1007/978-3-322-84904-5). 

The exFinder project is listed in the [Voila Gallery](https://voila-gallery.org/).
