Subject: [Caml-list] BigArray.Array2 vs Array.make_matrix
Date: Wed, 27 Nov 2002 22:22:25 -0500 [thread overview]
Message-ID: <3DE58BF1.936A93B4@ai.mit.edu> (raw)
> I was wondering what are the relative merits (in terms of speed,
> portability and ease
> of use) between using arrays of arrays, and the BigArray class.
>
> While web browsing, I saw a couple of people claim that BigArray is
> signigicantly slower than the standard array class:
>
> http://caml.inria.fr/archives/200105/msg00217.html
> claims BigArray is 3 times slower
>
> www.cs.cornell.edu/courses/cs612/2001sp/ projects/ocaml-arrays/OCaml.pd
> claims BigArray is about 10 times slower
>
>Is this still true, with the latest release? (3.04)
>
> Has anyone written some nice syntactic sugar for 2D matrices using
> either class?
> eg., so I can pretty print the matrix, or easily extract the num
> rows/columns?
> Plus an interface to some standard linear algebra code would be nice...
