This package  provides a library which is an extension for the

GNU Scientific Library (GSL). The latest version can be found at

http://savannah.nongnu.org/projects/marray/

It allows to define and manipulate marrays, multidimensional arrays of

arbitrary order and arbitrary dimension different for each

index. Marrays generalize vectors and matrices, and are well suited to

manipulate data grids.

The library interface is very similar to that of gsl_matrix, and most

of the functions that exist for gsl_matrix are also implemented for

marrays and have the same syntax.

Its sister project is "tensor", which defines a new type similar to marray

but with the same dimension for each index (for matrices, that would be

square matrices), and with all the common operations used with tensors,

including tensorial product, index contraction and index swapping. It is

suited to work with tensor algebra. "tensor" can be found at

http://savannah.nongnu.org/projects/tensor/

To install this software you first need the GNU Scientific Library

(GSL), that you can get from: http://sources.redhat.com/gsl/ . See the

detailed instructions in the file INSTALL in this same

directory. Briefly, all you need to do is:

  ./configure

  make

  make install

(for the last step you may need to be root).

If you took the files directly from the repository, you will need to

run ./autogen.sh first. That is:

  ./autogen.sh

  ./configure

  make

  make install

To use this library, compile your program with

  gcc -o myprog -lgslcblas -lgsl -lmarray myprog.c

That's it. Have fun!
