https://directory2p.fsf.org/wiki/MuTE_Toolbox
https://directory2p.fsf.org/wiki/MuTE_ToolboxMuTE Toolbox,A challenge for physiologists and neuroscientists is to map information transfer between components of the systems that they study at different scales, in order to derive important knowledge on structure and function from the analysis of the recorded dynamics. We propose a freeware MATLAB toolbox, MuTE (Multivariate Transfer Entropy), that implements four both Granger causality and transfer entropy estimators according to uniform and non-uniform embedding frameworks. The resulting eight methods can be easily compared showing all the pros and cons of the methodologies used to detect the directed dynamical information transfers. The toolbox provides a completely brand-new approach that bridges machine learning and information theory fields. MuTE is also able to perform bivariate and fully multivariate analyses. Furthermore, users can easily implement their own methods or change some features of the already existing approaches due to the modularity of the toolbox.,http://mutetoolbox.guru/,falseTue, 20 Oct 2015 13:32:14 GMTAlessandromontaltoMpc

https://directory2p.fsf.org/wiki/MpcMpc,'''GNU MPC''' is a complex floating-point library with exact rounding. It is based on the GNU MPFR floating-point library, which is itself based on the GNU MP library.
This is a C library for the arithmetic of complex numbers with arbitrarily high precision and correct rounding of the result. It extends the principles of the IEEE-754 standard for fixed precision real floating point numbers to complex numbers, providing well-defined semantics for every operation. At the same time, speed of operation at high precision is a major design goal.,https://www.gnu.org/software/mpc/,License:LGPLv3orlater,trueThu, 03 May 2018 09:50:38 GMTBendikkerMinfx

https://directory2p.fsf.org/wiki/McStasMcStas,McStas lets you model very precisely a neutron instrument described as a series of various components. A source component shoots each neutron randomly (Monte-Carlo), and the particle is then propagated through the different instrument components. These later act on the neutron characteristics (position, speed, direction, spin, etc.). Usually, one installs some detectors along the neutron path to monitor its characteristics and flux.,http://www.mcstas.org/,License:GPLv2orlater,falseWed, 01 Mar 2017 17:03:31 GMTAlejandroindependienteMIT Photonic Bands

https://directory2p.fsf.org/wiki/Light_Speed!Light Speed!,Light Speed! is an OpenGL-based program which illustrates the effects of special relativity on the appearance of moving objects. When an object accelerates past a few million meters per second, these effects begin to grow noticeable, becoming more and more pronounced as the speed of light is approached. These relativistic effects are viewpoint-dependent, and include shifts in length, object hue, brightness and shape. The moving object is, by default, a geometric lattice. 3D Studio and LightWave 3D objects may be imported as well. Best of all, the simulator is completely interactive, rendering the exotic distortions in real-time!,http://lightspeed.sourceforge.net/,Gpl2.1,falseMon, 27 Nov 2017 01:54:08 GMTDanmLibrsb
https://directory2p.fsf.org/wiki/Librsb
https://directory2p.fsf.org/wiki/LibrsbLibrsb,librsb is a library for sparse matrix computations featuring the Recursive Sparse Blocks (RSB) matrix format. This format allows cache efficient and multi-threaded (that is, shared memory parallel) operations on large sparse matrices. The most common operations necessary to iterative solvers are available, e.g.: matrix-vector multiplication, triangular solution, rows/columns scaling, diagonal extraction / setting, blocks extraction, norm computation, formats conversion. The RSB format is especially well suited for symmetric and transposed multiplication variants. On these variants, librsb has been found to be faster than Intel MKL's implementation for CSR. Most numerical kernels code is auto generated, and the supported numerical types can be chosen by the user at build time.
librsb implements the Sparse BLAS standard, as specified in the BLAS Forum documents.,http://librsb.sourceforge.net/,License:LGPLv3orlater,falseWed, 21 Feb 2018 16:59:54 GMTBendikkerLibquantum
