#Introduction

The Laplacian operator $\Delta u$ is the divergence of the gradient, that is the sum of the second-order partial derivatives $\nabla^2 u$ of a multivariate function, which represents the local curvature of this function. This operator is widely used for edge-detection[^1], as well as in partial-differential equations (Poisson, etc.), and other [...]

I have struggled with most solutions to convert and embed Jupyter notebooks into WordPress blog posts since I use Plotly as a graphic lib, as well as many LaTeX equations and images. Finally, I had to code my way through. Here is what I did :

1. Write the jupyter notebook

Nothing that you don’t know here. If you embed pictures in the notebook though, it would [...]
