Hi everyone,
I need to do a lot of matrix manipulation and it needs to be fast.
There seems to be a whole bunch of packages dealing with matrix
calculations on HackageDB. I am wondering, what is the current
state-of-the-art?
I started of using hmatrix [1] now. However, I eventually would like to
use some functions from the statisics-package [2]. They both use
different types for their vector representations. In hmatrix a vector
is of type Data.Packed.Vector. In the statistics package, vectors are
based on [3].
I found this:
http://www.haskell.org/haskellwiki/Linear_algebra
but the last post is from 2005. That is 6 years ago. What is the state
now? What would you recommend me to use?
I don't want to code and then realise in a few month, I made the wrong
decision. So, help is greatly appreciated.
Thanks,
Thomas
