1D PRESS (voxel selective NMR) pulse sequence.

==Syntax==

fid=press_1d(spin_system,parameters,H,R,K,G,F)

==Description==
Runs voxel-selective excitation and then records an NMR spectrum. This sequence must be called from the [[imaging.m]] context, which would provide H,R,K,G, and F.

==Arguments==

parameters.ss_grad_amp - the amplitude of slice selection
gradient, T/m

parameters.rf_frq_list - a vector of RF frequencies at each
pulse slice, Hz

parameters.rf_amp_list - a vector of RF amplitudes at each
pulse slice, rad/s

parameters.rf_dur_list - a vector of pulse slice durations,
in seconds

parameters.rf_phi - pulse phase at time zero

parameters.max_rank - maximum rank in the Fokker-Planck
pulse operator (2 is usually enough)

==Outputs==

fid - free induction decay of the NMR spectrum

==Examples==
See press_example_1d.m file in examples/imaging directory.
