ustment is made in cases
        where the polynomial is to be evaluated exactly at a data point.
        The paper reads:
        <pre>
          exact(xdiff==0) = 1;
        </pre>
        but it should read
        <pre>
          exact(xdiff==0) = j;
        </pre>
      </i>
    </p>

      <b>BARYCENTRIC_INTERP_1D</b> requires the R8LIB library.  The test also requires
      the TEST_INTERP_1D library.
