The interactive FDTD-toolbox for MATLAB is a simulation software to model and
simulate two dimensional optical systems in TE-polarization.
It was designed for educational purposes - no further knowledge of MATLAB or computational physics is required. The software is embedded in a graphical user interface in which all
the simulation parameters can be set. Furthermore, geometrical structures are defined via draggable forms which makes the program very intuitive and easy to use. Even difficult simulation structures can be set up in a few minutes.
The program works very efficient, accurate and reliable. To achieve this, a matrix-based algorithm according to Yee’s FDTD-method was implemented allowing easy
parallelization. Furthermore, perfectly matched layer (PML) boundary conditions and current like sources are included for realistic scenarios.

According to a recommendation i added changeable colormaps for the visualization. Furthermore some minor changes in program documentation were done
Improved language and added a direct link to the tutorials as requested by the users.
