Fortran-style multidimensional arrays in C++

Is there a C++ library which provides Fortran-style multidimensional arrays with support for slicing, passing as procedural parameter and decent documentation? I've looked into blitz++ but its dead!

I highly suggest Armadillo:

Armadillo is a C++ linear algebra library (matrix maths) aiming towards a good balance between speed and ease of use

It is a C++ template library:

A delayed evaluation approach is employed (at compile-time) to combine several operations into one and reduce (or eliminate) the need for temporaries; this is automatically accomplished through template meta-programming

A simple example from the web page:

#include <iostream>
#include <armadillo>

int main(int argc, char** argv)
{
    arma::mat A = arma::randu<arma::mat>(4,5);
    arma::mat B = arma::randu<arma::mat>(4,5);

    std::cout << A*B.t() << std::endl;

    return 0;
}

If you are running OSX the you can use the vDSP libs for free.

If you want to deploy on windows targets then either license the intel equivalents (MKL) or I think that the AMD vector math libs (ACML) are free.
