SIFTER pulse sequence.

Syntax

fid=sifter(spin_system,parameters,H,R,K)

Arguments

parameters.npoints - number of points in time evolution

   parameters.timestep     - simulation time step, seconds
   parameters.rho0         - initial state
   parameters.coil         - detection state
   parameters.pulse_opx    - pulse operator in X phase
