SOM Toolbox Online documentation http://www.cis.hut.fi/projects/somtoolbox/ som_divide [V,I]=som_divide(sMap, D, inds, mode) SOM_DIVIDE Divides a dataset according to a given map. [V,I]=som_divide(sMap, sData, [inds], [mode]) ARGUMENTS ([]'s are optional) sMap (struct or matrix) map struct or codebook (size munits x dim) sData (struct or matrix) data struct or matrix (size N x dim ) [inds] From which map units should the local data sets be constructed. Interpretation depends on mode argument. By default [1:munits]. 'class': (vector) munits x 1 matrix of class numbers 'index': (vector) K x 1 vector of map node indexes 'index': (matrix) K x k matrix of map node subscripts [mode] (string) 'index' or 'class', if inds is a vector of length

Unformatted text preview: munits, default is 'class', otherwise 'index'. RETURNS If mode == 'index' V (matrix) data vectors hitting the specified nodes (size K x dim) I (vector) corresponding data row indexes (size K x 1) If mode == 'class' (this can be used after using som_select) V (cell array) V{K} includes vectors whose BMU has class number K in the input matrix 'coord'. Note that values of K below 1 are ignored. I (cell array) corresponding data indexes in the cell array NOTE: if the same node is specified multiple times, only one set of hits is returned.
