Numerical generalised cumulant expansion route to the relaxation superoperator to second order, which is equivalent to Redfield theory.

Syntax

    R=ngce(H,dt)

Arguments

     H    - a cell array of spin Hamiltonian commutation
            superoperators obtained from an MD trajectory
     dt   - time step of the MD trajectory, seconds

Outputs

     R    - laboratory frame relaxation superoperator

Notes

The trajectory must be at least five times longer than the longest correlation time expected in the system.
