This code demonstrates vectorization concepts from the the paper
Immanuel Anjam, Jan Valdman: Fast MATLAB assembly of FEM matrices in 2D and 3D: Edge elements. Applied Mathematics and Computation 267, 252–263 (2015)
We extended techniques from the paper
Talal Rahman and Jan Valdman: Fast MATLAB assembly of FEM matrices in 2D and 3D: nodal elements, Applied Mathematics and Computation 219, 7151–7158 (2013)
to a fast assembly of FEM matrices using edge elements - Raviart-Thomas elements for Hdiv problems and Nedelec elements for Hcurl problems. In addition, vectorized higher order quadratures were added.

Please cite the paper if you find the code useful.
To compare the assembly times, call
"start_2D" or "start_3D" in the "example_comparison" directory.
You can also call
"start_2D" or "start_3D" in "example_majorant" and "example_eddycurrect" directories
to obtain solution of the functional majorant minimization in Hdiv space and a solution of a eddy current problem in Hcurl space.
