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 2.22.1 and dated 2025-05-19.

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.

Recent news:

2025-05-28: Release of the 2.22.1 version. New msColAutoScale, msRowAutoScale and msExtractTetraConnect routines. msPause and mfSortRows routines improved. msSortRows added. Many bugs fixed in both FML and FGL.
2025-03-13: Release of the 2.21.19 version. Fixes bugs in both FML and FGL. Integration via msQuad has been improved for infinite intervals. New autocorrelation routines mfXCorr and mfXCorr2. New routines to deal with Voronoi tesselations, both in FML and FGL. New physical units added. In Bar plot (msBar), for the X-axis, the numerical ticks labels may be replaced by any character strings.
2024-04-15: Release of the 2.21.5 version. msTriContourF accepts now disjoint zones in the used triangular mesh.
2024-03-25: Release of the 2.21.4 version. NaN values are now supported in msTriContourF and msTriFill, they are equivalent to lack of data.
2024-01-12: Release of the 2.21.1 version. GCC 4.9 is now the minimum version to build Muesli. Fixes few important bugs in both FML and FGL. NaN values are now supported in msTriContour, they are equivalent to lack of data. New behavior of mfCount, which behaves now like the Fortran intrinsic function 'count'. Sparse boolean mfArrays are now implemented. For GNU_GCC, all private components of some Muesli derived types are now really hidden, via an internal modification of the precompiled module files 'fml.mod' and 'fgl.mod'.
2023-11-20: Release of the 2.20.5 version: fix of an important bug which prevents to draw data using automatic axis.
2023-11-05: Release of the 2.20.4 version, which fixes a number of bugs, more or less important.
2023-03-23: Release of the 2.20.3 version. Redesign of the X11 graphic engine, and many improvements of the graphic routines. Many bugs fixed. Quadratic Bézier segments can now be drawn by msPlotQuadrBezier. API modified for some FGL routines. Many improvements in routines dedicated to the build of triangle mesh connectivity. EPS and PDF drivers improved (generated files are more compact). New routines for filled contours (mf/msContourF and mf/msTriContourF)
