In the definition for x, x_max will be included in the grid. For y, it won't. Is this intended?
Getting the following error on windows:

Is there any way I could interface modesolverpy with matplotlib instead of gnuplot (if this is the issue)?
how could we have python2 and python3 compatibility?
Dear Jtambasco,
I copied your program on modesolverpy for mode hybridization. The program does not give the output plot as shown on your page, especially the structure_n_effs.png file is supposed to have TE fraction shown as well but it does not appear on the plot. Please, I request you to make necessary adjustment.
On line 372 in structure_base.py the height of a Slab Class feature is first discretised and then another y_step is added to the height:
height_discretised = self.y_step*((height // self.y_step) + 1)
Even if you choose a stepsize for the layers, such that is correctly discretised (e.g. 10nm stepsize for a 100nm layer), this line of code will still add another self.y_step (in this case 10nm) to the layer thickness and cause it to be larger (110nm) instead. While this might not be an issue for small stepsizes or a low amount of layers, this causes problems for larger stepsizes or many layers, such as in Bragg-mirror structures.
I am unsure why the self.y_step is added, maybe there is a solid reason for it, but in my case it simply causes the layers to have wrong thicknesses.
