Description

The exFinder web application calculates and visualizes interactively the extreme values of multivariate functions: $f:\mathbb{R}^2\to\mathbb{R}$

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].

The exFinder project is listed in the Voila Gallery.

Usage: Enter a function in x and y in Pythonic form into the input field and click on the update button.

iexfinder's Issues

Show equation system for gradient = zero

Show the equation system \nabla f(x, y ) = (0, 0)^T in HTML

In order to show a step by step procedure

Add a Contour plot

Add a contour plot (with plotly, as the surface plot) as in wolfram alpha

Readthe Docs Sphinx documentaion

Include readthedocs Sphinx documentation:

Usage
Theory
References
Gallery (some examples with surface plots)

Extension to functions of a complex variable

If the argument is complex, i.e. depending on x + i *y or on z, then analyse and plot |f(z)|

Include the Points of the extreme values

Inlcude colored points of the extreme values as in Wolfram Alpha
