Matlab to SPINS grid ordering, for a 2D domain with periodic (or free-slip) conditions in the x-direction and free-slip conditions in the z-direction and a flat bottom boundary.
It solves the DJL equation for solitary waves or the Taylor-Goldstein equation for traveling/standing linear waves, interpolates the u, w and rho fields onto a regular (non-Cheb) grid, and then saves the data as SPINS input files (for wave_reader_x).
Getting the code
The code is hosted in a git repository on the UW git server. To extract the code from the git repository, go to (or create) the directory in which you want to run simulations using SPINS. In that directory, type git clone https://git.uwaterloo.ca/c2xu/matlab2spins.git. This will create a directory called spins2matlab where the code is stored.
