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);
