%SOMUNPAK Replaces node weights in SOM.

%	Description
%	NET = SOMUNPAK(NET, W) takes a SOM data structure NET and weight
%	matrix W (each node represented by a row) and puts the nodes back
%	into the multi-dimensional array NET.MAP.
%
%	The ordering of the parameters in W is defined by the indexing of the
%	multi-dimensional array NET.MAP.
