som_projections_plot(pmode,varargin)
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
