### Question:
LUT1 { public Grid getMagnitudeGrid5() { return magnitudeGrid; } private  LUT1(Grid magnitudeGrid, Grid exponentGrid); static LUT1 read(File file); Grid getMagnitudeGrid5(); Grid getExponentGrid5();  }### Answer:
@Test public void testMagnitudeGrid() { final Grid grid = lut1.getMagnitudeGrid5(); assertNotNull(grid); assertEquals(0.9132683f, (float) grid.getSampleDouble(0, 4), 0.0f); assertEquals(0.7707501f, (float) grid.getSampleDouble(39, 3), 0.0f); }
