Hello,
I have two other questions about Bigarray :
- - Bigarray seems to provide a relatively low level interface to general
multi-dimensional numerical arrays in OCaml. Do you know about a helper
library that provide higher level numerical functions such as those
provided in the Python Numeric package ? What I miss most are Ufuncs
(universal functions defined here :
http://www.pfdubois.com/numpy/html2/numpy-7.html#30906 ).
- - what is the difference of performance between Bigarray based
computation and Python Numeric based computation ?
Thanks for any hint !
