planes3d

 PLANES3D Draws 3D component planes

 CALLS
 planes3d(smap)
 planes3d(u,feat)
 planes3d(u,feat,dims)
 planes3d(u,feat,dims,featnames)

 Notation:
         P = Number of features
         S = Number of lattice points

 smap:      Som structure
 u:         Grid data matrix (3 x S). Each column represents a grid node
 feat:      Features data matrix (P x S). Each row is a feature. Each 
            column can be see as the coordinates of a codebook vector
 dims:      Cell array {1 x 3} with the size of the SOM lattice in the 3 
            dimensions of the visualization space. (if not specified, the 
            lattice is assumed with equal number of elements in each 
            dimension)
 featnames: Cell array {1 x P} with the names of the features to be
            represented
