-------------3 FINITE DIFFERENCE SOLVERS---------------------
-------------------------------------------------------------

----------------------FDTDCN---------------------------------

Here the Crank Nicolson Method is used. 
Format of data obtained via integration is as follows:

Spatial Coordinate | real(psi) | imag(psi) | |psi|² 

Decay:
To get energy of wave use fitprogram like GNUPLOT with 
'decay.txt'

First column is the elapsed time, second and third column are 
the real and imaginary parts.

---------------------FDTD1D----------------------------------

Explicit Finite Difference Time Domain Method.
Format of data via integration is as follows:

Spatial Coordinate | real(psi) | imag(psi) | |psi|² 

Decay:
To get energy of wave use fitprogram like GNUPLOT with 
'decay.txt'

First column is the elapsed time, second and third column are 
the real and imaginary parts.

---------------------FDTD3D----------------------------------

Explicit Finite Difference Time Domain Method in three dimen-
sions.
Format of data is as follows:

x-Coordinate | y-Coordinate | z-Coordinate | real(psi) | imag(psi) | |psi|² 

-------------------------------------------------------------
To edit parameters change code in .cpp file
(Be careful if changing Number of Nodes in FDTD3D, very memory consuming)

To run program go to directory of .cpp file and type in the console:
g++ Filename.cpp -o Progname
and then
./Progname
