public RealMatrix adjustPrecision() {
    DiagonalMatrix D = new DiagonalMatrix(eigenA.getRealEigenvalues());
    for (int i = 0; i < R.length; ++i) {
        double lambda = D.getEntry(i, i);
        D.setEntry(i, i, lambda / (R[i] * R[i]));
    }/*w ww.j a va  2s . c om*/
    RealMatrix ret = eigenA.getV().multiply(D.multiply(eigenA.getVT()));
    return ret;
}
