Question

Which library do you use for N-dimensional arrays?

I use blitz++ at work and I really dislike some aspect of it.
Some aspect of it are even dangerous. The need for resizing before
using operator=. A(Range::all(), Range::all()) throws for an (0,0)
matrix, etc. and the linear algebra operations are to be
done via clapack.

I used and loved eigen. I appreciate its “all-in-header” implementations,
the C++ syntactic sugar, and the presence of all the linear algebra operations
I need (matrix multiplication, system resolution, cholesky…)

What are you using?

Answer 1

boost::array and also boost::MultiArray. There’s also a pretty good linear algebra package in boost called uBLAS
