P = som_order_cplanes(sM, varargin)
SOM_ORDER_CPLANES Orders and shows the SOM component planes.
P = som_order_cplanes(sM, [[argID,] value, ...])
som_order_cplanes(sM);
som_order_cplanes(sM,'comp',1:30,'simil',C,'pca');
P = som_order_cplanes(sM);
Input and output arguments ([]'s are optional):
sM (struct) map or data struct
(matrix) a data matrix, size * x dim
[argID, (string) See below. The values which are unambiguous can
value] (varies) be given without the preceeding argID.
P (matrix) size n x * (typically n x 2), the projection coordinates
Here are the valid argument IDs and corresponding values. The values
which are unambiguous (marked with '*') can be given without the
preceeding argID.
'comp' (vector) size 1 x n, which components to project, 1:dim by default
'simil' *(string) similarity measure to use
'corr' linear correlation between component planes
'abs(corr)' absolute value of correlation (default)
'umat' as 'abs(corr)' but calculated from U-matrices
'mutu' mutual information (not implemented yet)
(matrix) size n x n, a similarity matrix to be used
'proj' *(string) projection method to use: 'SOM' (default),
'pca', 'sammon', 'cca', 'order', 'ring'
'msize' (vector) size of the SOM that is used for projection
'show' *(string) how visualization is done: 'planes' (default),
'names', or 'none'
'mask' (vector) dim x 1, the mask to use, ones(dim,1) by default
'comp_names' (cell array) of strings, size dim x 1, the component names
The visualized objects have a callback associated with them: by
clicking on the object, the index and name of the component are printed
to the standard output.
