Plot 1d.m

1D plotting utility. Uses the same parameters structure as 1D pulse sequences. Input syntax:

             plot_1d(spin_system,spectrum,parameters)

Input parameters:

   parameters.sweep              sweep width, Hz

   parameters.spins              spin species, e.g. {'1H'}

   parameters.offset             transmitter offset, Hz

   parameters.axis_units         axis units ('ppm','Gauss',
                                 'mT','T','Hz','kHz','MHz')

   parameters.derivative         if set to 1, the spectrum is
                                 differentiated before plotting

   parameters.invert_axis        if set to 1, the frequency axis 
                                 is inverted before plotting

Any extra arguments given to this function will be passed to the built-in Matlab function plot().
