        void updateDictionary​(smile.math.matrix.DenseMatrix dictionary,
                      smile.math.matrix.DenseMatrix auxMatrixU,
                      smile.math.matrix.DenseMatrix auxMatrixV)
               throws MatrixDimensionMismatch,
                      VectorDimensionMismatch
        Does a dictionary update based on some algorithm utilizing the input matrices.
        Parameters:
        dictionary - The dictionary to be updated.
        auxMatrixU - An auxiliary matrix used to update the dictionary.
        auxMatrixV - Another auxiliary matrix used to update the dictionary.
        Throws:
        MatrixDimensionMismatch - Thrown when the operations cannot be completed because the dimensions of the dictionary and the two auxiliary matrices mismatch.
        VectorDimensionMismatch - Thrown when an operation cannot be done be cause a dimension in the auxiliary matrices do not work with the input dictionary.
