Re: [Liberty-eiffel] SoC 2016

[Bernd Schoeller]

Just to add to this, I am currently implementing a MATRIX class and 
related linalg function for the other Eiffel compiler. I am trying to 
build something like numpy, but - of course - with a better design and 
consistent and powerful interface.

https://github.com/schoelle/algae

I am not saying that you should use this: it is probably not much 
further developed than starting from scratch and the two Eiffel 
compilers do differ quite a bit.

But perhaps we can have an open exchange on design decisions, as my 
stuff is also still strong 'work in progress' and I have no clue how I 
want to implement certain things like the different matrix decomposition 
functions and linear regression.

Good luck,
Bernd

PS: A book that I can very much recommend:

https://books.google.co.uk/books/about/Matrix_Computations.html?id=5U-l8U3P-VUC

I found the 3rd edition here for free:
