Stitch.m

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)

Parameters

            L - spin system Liouvillian

    rho_stack - state vector stack from the forward part of
                the simulation

   coil_stack - coil vector stack from the backward part of
                the sumulation

     mec_oper - cell array of operators in the midpoint event
                chain, e.g. {Lx,L,Sy}

     mec_time - cell array of durations of each event at the
                midpoint of the t2 evolution period

    t1.nsteps - number of time steps in t1

    t2.nsteps - number of time steps in t2

    t3.nsteps - number of time steps in t3

         tdir - time direction for state and coil propagation,
                the default is '+-'

Outputs

          fid - three-dimensional free induction decay
