See COLORMAP.   color    (matrix) size N x 3 x dim, RGB matrix  Purpose of this function is to calculate fixed RGB colors that are similar to indexed colors with the specified colormap. This is because some SOM Toolbox visualization functions (as SOM_GRID) do not use indexed colors  if the underlying Matlab function (e.g. PLOT) do not use indexed colors EXAMPLE %%% Visualize three variables in a map using som_grid: %%% Give coordinates for the markers according to variables 1 and 2, and  %%% 'indexed colors' according to variable 3.  som_grid(map.topol.lattice,map.topol.msize,'Coord',map.codebook(:,1:2), ...
