This is the numerical model for the 2-site Bloch-McConnell equations for R1rho data.
This code originates from the Skrynikov & Tollinger code (the sim_all.tar file
https://gna.org/support/download.php?file_id=18404 attached to https://gna.org/task/?7712#comment5).
Specifically the funNumrho.m file.
This commit follows step 3 of the relaxation dispersion model addition tutorial
