Here is another resource I came across when learning about the conjugate gradient method for a class on finite elements. I wish I had found this back then!

Thanks ! Are there other great math papers or articles with a similar "without the agonizing pain" approach, for other topics that might be interesting ?

This is actually the basis of the online article, see the acknowledgments.
