SOM Toolbox Online documentation http://www.cis.hut.fi/projects/somtoolbox/ som_lininit Purpose Initializes a SOM linearly along its greatest eigenvectors. Syntax sMap = som_lininit(D); sMap = som_lininit(D,sMap); sMap = som_lininit(D,'munits',100,'hexa'); Description Initializes a SOM linearly. If necessary, a map struct is created first. The initialization is made by first calculating the eigenvalues and eigenvectors of the training data. Then, the map is initialized along the mdim greatest eigenvectors of the training data, where mdim is the dimension of the map grid. References Kohonen, T., "Self-Organizing Map", 2nd ed., Springer-Verlag, Berlin, 1995, pp. 106-107. Required input arguments D The training data. (struct) Data struct. If this is given, its '.comp_names' and '.comp_norm' fields are copied to the map struct. (matrix) data matrix, size dlen x dim Optional input arguments argID (string) Argument identifier string (see below). value (varies) Value for the argument (see below).
