org.apache.mahout.math.matrix.impl.DenseDoubleMatrix1D.assign()
Sets all cells to the state specified by values. values is required to have the same number of cells as the receiver.
The values are copied. So subsequent changes in values are not reflected in the matrix, and vice-versa. @param values the values to be filled into the cells. @return this (for convenience only). @throws IllegalArgumentException if values.length != size().

        // so we need to calculate the centroid here once again based
        // on the cluster's documents.
        final DoubleMatrix1D centroid = new DenseDoubleMatrix1D(termDocumentMatrix.rows());
        for (IntCursor d : documents)
        {
            centroid.assign(termDocumentMatrix.viewColumn(d.value), Functions.PLUS);
        }


        final List<String> labels = Lists.newArrayListWithCapacity(labelCount);


        final int [] order = IndirectSort.mergesort(0, centroid.size(),
