umat | Set a U-matrix to be used while visualizing a graphic structure |
<graphic> | name of the graphic structure |
-umat <umat> | name of the U-matrix data to be used |
umat <graphic> -rm | Clear the U-matrix presentation |
This command sets a U-matrix to be used while visualizing the specified graphic structure. The distances between neurons are illustrated as distances between the rectangles in a graphical presentation. See the umat command (section 5.1.7) for information about how U-matrices are calculated.
Example (ex7.10): Three weights, rm_w, zn_w and age_w, are selected to be the basis of distance computing. Then a U-matrix is computed and selected into graphic structure grp1.
