therealjakejordan/gas_porosity_wave_JGR: Long period eruptive precursors at silicic volcanoes

The provided files generate the steady state and time dependent solution to model equations in the mansucript "The effects of degassing on long period eruptive precursors at silicic volcanoes" by Jordan and others. Additionally, data may be saved and processed so stem plots for visualizing the power spectrum for the growth of gas waves may be visualized. A brief symbolic code for solving the analytical growth curve (appendix B) is also provided.
