Tensor is a library for multidimensional array representation and processing. It is an extension of GSL - the GNU Scientific Library, which is a collection of numerical routines for scientific computing.
You would need the GSL library in order to use this extension. A copy can be downloaded from a nearby GNU mirror http://ftpmirror.gnu.org/gsl/.
Detailed installation instructions can be found in the included README and INSTALL files in the downloaded package, however, the shell command
./configure && make && make install
should suffice to configure, build, and install GSL on most systems.
The Tensor library can be installed in a similar fashion. Run the following shell commands in its top-level directory:
mkdir build
cd build
../configure
make -j
make -j check
make install
Have a look at the included INSTALL file for customised build instructions.
A reference manual is included in GNU Texinfo format. It should be available for reading on your system using the info tensor command once the library is installed.
