Ultrafast multiple-quantum NMR, a literal implementation of Figure 1A from (http://dx.doi.org/10.1002/cphc.201800667).

Syntax

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

Parameters

    parameters.dims           -  size of the sample, m

    parameters.npts           - number of grid points in the sample

    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.offset         - offset, Hz

    parameters.Ga             - acquisition gradient, T/m

    parameters.deltat         - timestep for acquisition, s

    parameters.pulsenpoints   - number of points in the pulse shape

    parameters.BW             -  bandwidth of the pulse, Hz

    parameters.Ge             -  encoding gradient, T/m

    parameters.Te             - duration of the pulse, s

    parameters.chirptype      - can be 'wurst' or 'smoothed'

    parameters.smfactor       - smoothing factor for the pulse

    The last five parameters (H,R,K,G,F) are built automatically by imaging.m context function 
    when this sequence is called from that context.

Outputs

    fid -  free induction decay of the ultrafast NMR spectrum
