som_bmucolor

bmu_colors=som_bmucolor(bmus, m, colors);

 SOM_BMUCOLOR Returns the colors of the bmus according to a map colorcode

 bmu_colors=som_bmucolor(bmus, msize, colors);

 INPUT ARGUMENTS ([]'s are optional)

 bmus   (matrix) Nx1 vector of BMU indexes
 msize  (map struct, topol struct or 1x2 vector) 
          gives the map grid size 
 colors (matrix) colormap(s): munits x 3 x d matrix of RGB vectors

 OUTPUT ARGUMENTS 

 bmu_colors (Nx3xd matrix) color of the data point according to its BMU's 
              color(s).

 Idea is to get a color for each data point that links it to its BMU. 

 EXAMPLE

 We want to show how an time series is projected  to a map. Instead of 
 a trajectory, we use 'color linking'

 map=som_make(multi_dim_signal); 
 bmus=som_bmu(map,multi_dim_signal);
 Colors=som_bmucolor(bmus, map, som_colorcode(map,'rgb1'));
 colorsignal(Colors, multi_dim_signal);
