Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.

Compiling with Eigen

  • module load eigen

To compile an application with the Eigen header files, load the eigen module and use the compiler wrappers cc, CC, or ftn in the usual way. The relevant header files will be introduced automatically.

The header files are located in /work/y07/shared/libs/core/eigen/3.4.0/, and can be included manually at compilation without loading the module if required.

Version history

  • Module eigen/3.4.0 installed October 2021

Compiling your own version

The current supported version on Archer2 can be built using the following script

$ wget
$ tar xvf eigen-3.4.0.tar.gz
$ cmake eigen-3.4.0/ -DCMAKE_INSTALL_PREFIX=/path/to/install/location
$ make install
where the -DCMAKE_INSTALL_PREFIX option determines the install directory. Installing in this way will also build the Eigen documentation and unit-tests.
