%Convert data to columns and put them together to a matrix
%
%Input:
%  VARARGIN - arrays of data
%
%Output:
%  ARRAY   - matrix ot the size PROD(DIMS) x COUNT with the data arrays
%            as its columns
%  DIMS    - sizes of the data arrays
%  COUNT   - number of the data arrays
%
%Notes:
%  All input data should have the same dimensions.
%  In only one array is given, it is transformed to a matrix.
