press_1d.m

1D PRESS (voxel-selective NMR) pulse sequence that performs voxel-selective excitation and records an NMR spectrum; it must be called from the imaging.m context, which provides H,R,K,G, and F.

Syntax

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

Parameters

   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
