19:41, 8 April 2020 1 The Derivative Revisited.pdf (file) 371 KB In 1979 Ken Iverson wrote a paper on the derivative as part of the ACM APL Conference. That paper included a section summarizing the rules for the derivatives of compound formulations such as f×g. His summary omits the derivation of these rules. This article aims to restate these rules in more modern notation and provide derivations for Iverson's results. 2

21:55, 16 July 2024 Tensors.pdf (file) 1.61 MB This is an introduction to tensors written in APL. Einstein notation is slick. It's compact and powerful. In that regard, it has much in common with APL. This introduction starts with the notion of fields and coordinate transformations and carries through to the generalized covariant derivative. 1
