Ultrafast 3D DOSY-COSY pulse sequence. Syntax:
fid=spendosycosy(spin_system,parameters,H,R,K,G,F)
Parameters:
parameters.dims size of the sample in m
parameters.npts number of spin packets
parameters.spins nuclei on which the sequence runs
parameters.deltat timestep for acquisition
parameters.npoints number of acquired points for each
gradient readout
parameters.nloops number of loop, where each loop consists of
a positive and a negative readout
parameters.Ga acquisition gradient in T/m
parameters.pulsenpoints number of points in the pulse shape
parameters.smfactor smoothing factor for the pulse
parameters.Te duration of the pulse
parameters.BW bandwidth of the pulse
parameters.Ge encoding gradient in T/m
parameters.Gp coherence selection gradient in T/m
parameters.Tp duration of the coherence selection gradient
parameters.chirptype can be 'wurst' or 'smoothed'
H Fokker-Planck Hamiltonian
R Fokker-Planck relaxation superoperator
