MUESLI: a free numerical and graphical library

MUESLI library

What is MUESLI?

MUESLI is a free numerical and graphical library, written mainly in Fortran 95 and developped by Édouard Canot.

For a first introduction, see the User Guide.

The available release is numbered 2.23.0 and dated 2025-12-12.

for Linux systems, contrary to the past, only two Fortran 95 compilers are supported:

GNU gfortran, version ≥ 4.9 (version numbers up to 15 are ok)
INTEL ifort, version ≥ 13 (version numbers 11 and 12 may work, but are no longer supported)

packages for Ubuntu

those for Fedora

for a Windows systems, WSL (Windows Sublayer for Linux) is now mature and support many releases of Ubuntu (see for example Ubuntu 22.04 on WSL). Once Ubuntu (or another linux distribution) is installed as a virtual machine, you can install yourself MUESLI.
MinGW-w64 is now unsupported.

Mac OS X is now unsupported.

MUESLI needs also a C and a C++ compiler. GCC and INTEL actually constitute compiler suites, which provide their own C and C++ compilers.

BLAS / LAPACK must be available on the target machine. The following versions (older ones may or may not work) are recommended: 3.7.1 (Jun 25, 2017), 3.8.0 (Nov 12, 2017), 3.9.1 (Apr 1, 2021), 3.10.1 (Apr 12, 2022), 3.11.0 (Nov 11, 2022) or 3.12.1 (Jan 8, 2025).
They can be get here.

The numerical part (FML) contains more or less 420 user-available routines and around 2860 unitary tests. As far as we know, this whole numerical library doesn't contain any memory leak (or very few — thanks to valgrind).

MUESLI is not a thread safe library.
