[Haskell-cafe] Is anyone working on a sparse matrix library in Haskell?

[Adrien Haxaire]

Hello,

I started a FEM library, funfem [1], but I stopped it for the moment; Haskell 
is my hobby and I work on FEM all day long, I prefer to focus on orthogonal 
problems for home projects. It is a very naive implementation. Far from a 
version 0.0.1 too, i.e. unusable at the moment. 

I did not test the performance as it was not my main goal, so the following 
may not be completely relevant to your purpose.

I define a type Tensor [2], which is a sparse matrix based on Data.Map. Not 
sure how efficient it is, I chose to start simple. The resulting conjugate 
gradient [3] is very clear.

Please let us know how it goes, it's good to see more traction towards Haskell 
from our field, and I'll be glad to use your library !

Best regards,
Adrien
