lottie vectors
Create, display and process 2D vectors in a 3D window.
... something acting on a position with direction and magnitude. Finally you can give each position a tag to display on screen. This could be a common math symbol or greek letter, start/end signposts, or a number of the position either from the begining or after a reset. After all the information has been loaded for your dataset. Either passed over the command line, or as a text file. Lottie Vectors displays inside a figure that you can resize, rotate and turn 2D positions into a 3D picture. -

matlab2tikz
Converts MATLAB®/Octave figures to TikZ/pgfplots figures
matlab2tikz is a MATLAB(R) script to convert native MATLAB(R) figures to TikZ/Pgfplots figures that integrate seamlessly in LaTeX documents. matlab2tikz supports the conversion of most MATLAB figures, including 2D and 3D plots. For plots constructed with third-party packages, your mileage may vary. Sometimes, MATLAB makes it hard to create matching LaTeX plots by keeping invisible objects around or stretching the plots too far beyond the bounding box. -

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... -
