A collection of packages providing extra functionality for GNU Octave
Octave-Forge is a central location for collaborative development of packages for GNU Octave. The Octave-Forge packages expand Octave's core functionality by providing field specific features via Octave's package system. See https://octave.sourceforge.io/packages.php for a list of all available packages. GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable. Refer to https://www.octave.org for more information.

Dynamics of quantum systems, controlled by external fields
WavePacket is a program package for numerical simulation of quantum-mechanical wavepacket dynamics for distinguishable particles. It can be used to solve one or more (i.e. coupled channels) time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations. Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can simulate modern experiments using ultrashort light pulses in photo-induced physics or chemistry, including quantum optimal control. The graphical capabilities allow visualization 'on the fly', including Wigner transforms to phase space. A description of WavePacket can be found in our manuscript at http://dx.doi.org/10.1016/j.cpc.2016.12.007. For examples / movies, see also the Wiki pages of the WavePacket main project. First established in 2004, the present Matlab version is in a stable, mature state. Further development mainly by Burkhard Schmidt at Free University Berlin

Open source 3D Matlab Isogeometric Analysis Code
Isogeometric analysis (IGA) is a fundamental step forward in computational mechanics that offers the possibility of integrating methods for analysis into Computer Aided Design (CAD) tools and vice versa. The benefits of such an approach are evident, since the time taken from design to analysis is greatly reduced leading to large savings in cost and time for industry. The tight coupling of CAD and analysis within IGA requires knowledge from both fields and it is one of the goals of the MIGFEM is to provide a simple-to-understand IGA FEM code. The work is funded under the FP7 Initial Training Network Funding under grant number 289361 'Integrating Numerical Simulation and Geometric Design Technology.'
