**ising_2d_simulation_test**,
a FORTRAN90 code which
calls ising_2d_simulation(), which
carries out a Monte Carlo simulation of a 2D Ising model,
using GNUPLOT to create graphics images of the initial and final configurations.

ising_2d_simulation, a FORTRAN90 code which carries out a Monte Carlo simulation of an Ising model, a 2D array of positive and negative charges, each of which is likely to flip to be in agreement with neighbors, using gnuplot() to make images of the initial and final configurations.

- ising_2d_simulation_test.sh, runs all the tests.
- ising_2d_simulation_test.txt, the output file.

- ising_2d_initial.txt, GNUPLOT commands to plot the initial configuration.
- ising_2d_initial.png, a plot of the initial configuration.
- ising_2d_final.txt, GNUPLOT commands to plot the final configuration.
- ising_2d_final.png, a plot of the final configuration.
