By default, the current axes is used (GCA). For the function to work, the plot in the axes must have been created with the SOM_CPLANE function (or SOM_SHOW). Launches a GUI which allows user to select nodes from plane by clicking them or by choosing a region (a polygon). Middle mouse button: selects (or clears selection of) a single node Left mouse button: lets user draw a polygon Right mouse button: selects (or clears selection of) the units inside the polygon From the GUI, the color (class) is selected as well as whether but buttons select or clear the selection from the units. The buttons on the bottom have the following actions: 'OK' Assigns the class identifiers to the 'ans' variable in workspace. The value is an array of class identifiers: strings (cellstr) if the c_vect was an array of strings, a vector otherwise. 'Clear' Removes marks from the plane. 'Close' Closes the application. See also SOM_SHOW, SOM_CPLANE.</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
