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); See also SOM_COLORCODE.</PRE><p><hr><br><center>[ <a href="somtoolbox.html">SOM Toolbox online doc</a> ]</center><br><!-- Last updated: May 30 2002 --></body></html>⌨️ 快捷键说明
