Syntax

       fid=psyche_1d(spin_system,parameters,H,R,K,G,F)

Arguments

parameters.coil           detection state

parameters.spins          nuclei on which the sequence runs

parameters.g_amp          gradient amplitude (T/m)

parameters.dims           size of the sample (m)

parameters.npts           number of discretization points in the grid

parameters.sweep          spectral range (Hz)

parameters.npoints        number of points in the sweep

parameters.zerofill       number of points for the zero filling

parameters.diff           diffusion constant (m^2/s)

H                         Fokker-Planck Hamiltonian

R                         Fokker-Planck relaxation superoperator

K                         Fokker-Planck kinetics superoperator

G                         Fokker-Planck gradient superoperators

F                         Fokker-Planck diffusion and flow superoperator

Returns

1D spectrum of the PSYCHE experiment

Notes

The last five parameters are built automatically by imaging.m context function when this sequence is called from that context.
