function ind = som_cod2ind(msize,cind)

%SOM_COD2IND Matlab linear index from SOM_PAK style linear indeces.
%
% ind = som_cod2ind(msize,cind)
%
%  ind = som_cod2ind([10 15],44);
%  ind = som_cod2ind(sMap,44);
%  ind = som_cod2ind(sMap.msize,44);
%  ind = som_cod2ind([10 15],[44 13 91]');
%
%  Input and output arguments: 
%   msize  (struct) map or topology struct
%          (vector) size 1 x m, specifies the map grid size
%   cind   (vector) size n x 1, SOM_PAK style linear indeces for n map units
%                   (row first, then column)
% 
%   ind    (vector) size n x 1, Matlab linear indeces
