plotFF3D
========
```{function}  plotFF3D(nf2ff,varargin)
```
Full definition:
```{code-block} matlab
h = plotFF3D(nf2ff,varargin)
```

 plot normalized 3D far field pattern

input:
- nf2ff:      output of CalcNF2FF

variable input:
- 'freq_index':    use the given frequency index, see nf2ff.freq
                   default is 1
- 'logscale':      if set, show far field with logarithmic scale
                   set the dB value for point of origin
                   values below will be clamped
- 'normalize':     true/false, normalize linear plot
                   default is false, log-plot is always normalized!

example:

    plotFF3D(nf2ff, 'freq_index', 2, 'logscale', -20)
