Hi Greg, Elementary, my dear Watson!
I don’t know what you mean by “with another commit” – it doesn’t have to be me that does these things, pull requests are just great. It’s a pity your drive isn’t working (I assume you mean SSD, solid-state disk), since that code sounds really good – any code that matters is best kept in a GitHub repo, limiting how much a hardware failure can destroy. We have a Data::Frame module that got updated recently, and the stats stuff may exist in PDL::Stats, but it would be good to compare with what you have! And thank you for your contributions, then and now!

What an investigation ! You could be a good detective I think 😉 And about a pull request I will do it. I though you would want to add this modification with another commit. And yes it’s me so. I guess I wanted to add different Matrix types, presumably based on the PDL Matrix class, trangular, diagonal etc. Idea abandoned but if I remember correctly I preferred to use the nd-array concept for the use of statistical analysis of arrays, Data Fame for example. I have on an old SDD, an advanced statistical module with usual operations (mean, var etc.), Data Frame which were printed with each row and column denomination (a new class), hypothesis testing stuff, ANOVA and the like, interface to all operations on distributions (normal, binomial, etc.) from R and nmath C libraries (included in the module), Principal Component Analysis, several factorial analysis (different rotation matrices) and the like. It’s a pity I can not read this SDD for now. I don’t even know if it’s still readable and only buying an USB interface from China would be possible I think. No professional where I live as far as I know has this material. And last time my order from Amazon Market was cancelled three weeks later. Maybe one day. In any case, thank you, Keep up the good work! __ Greg Le ven. 15 avr. 2022 à 14:38, Ed . <ej...@hotmail.com<mailto:ej...@hotmail.com>> a écrit : Hi Greg, https://metacpan.org/release/ELLIPSE/PDL-LinearAlgebra-0.01/view/Special/Special.pm (the first CPAN version of PDL::LinearAlgebra) has the same bit, and it’s released by one “Grégory Vanuxem”. The “someone” wouldn’t happen to be you back in 2005? ;-) It’s easiest for me (as the humble PDL maintainer) if this sort of thing is submitted as a pull request that I can just merge with one click. GitHub allows one to “edit” a file (the pencil icon top right of https://github.com/PDLPorters/pdl-linearalgebra/blob/master/lib/PDL/LinearAlgebra/Special.pm) which will automatically fork the repo if you’re not already a collaborator on it, and lets you then pull-request that with a couple of clicks just in the web UI. You don’t even need to clone the repo locally!

I have not found the commit so I don't know how to comment on the file at GitHub. Apparently someone began to implement a Matrix type but I may be wrong here. No pull request as it's too simple.
