    double[][] value = { { 1.0, 2.0 }, { 3.0, 4.0 } };
    DenseDoubleMatrix mat = new DenseDoubleMatrix(2, 2, value);
    SparseDoubleVector vec = new SparseDoubleVector(2);
    vec.setRowId(0);
    vec.set(0, 1.0);
    SparseDoubleVector vec_1 = new SparseDoubleVector(2);
    vec_1.setRowId(1);
    vec_1.set(1, 1.0);
    mat.plusBy(vec);
    mat.plusBy(vec_1);
    assertEquals(2.0, mat.get(0, 0));
    assertEquals(2.0, mat.get(0, 1));
    assertEquals(3.0, mat.get(1, 0));
    assertEquals(5.0, mat.get(1, 1));
