 SOM_PROJECTIONS_PLOT Projection visualizations.
 som_projections_plot(pmode,varargin)
   [cPCAarg, Pdata, Pproto] = som_projections(D,sM);
   som_projections_plot('scatter',Pdata(:,1:3))
   som_projections_plot('scatter',Pproto(:,1:3),Pproto(:,5:7),5,sM)
   som_projections_plot('residuals',Pdata(:,1:4))
   som_projections_plot('scree',cPCAarg{3})
 The other arguments depend on the pmode:
  pmode = 'scatter'
     arg1: Co     (matrix) coordinates
     arg2: color  (matrix) color vectors
                  (string) colorstring ('k' by default)
     arg3: psize  (scalar) point size
     arg4: sT     (struct) topology struct, if map grid is drawn
  
  pmode = 'residuals'
     arg1: Co     (matrix) coordinates (2 first columns) + residuals (the rest)
     arg2: color  (string) colorstring ('k' by default)
  pmode = 'scree'
     arg1: eigval (vector) vector of eigenvalues
