Stitching function for bidirectionally propagated 3D NMR pulse sequences. Propagate your initial condition forward to some midpoint, propagate your detection state backward to the same midpoint and use this function to obtain the 3D free induction decay (http://dx.doi.org/10.1016/j.jmr.2014.04.002) at the price of two 2D simulations.
Syntax
fid=stitch(spin_system,L,rho_stack,coil_stack,mec_oper,mec_time,t1,t2,t3,tdir)
Arguments
