Method Detail

computeStep_cauchy

public void computeStep_cauchy()

Pick a step less than the Cauchy step and see if the CauchyStep produces the same output as DoglegStep

computeStep_GaussNewton

public void computeStep_GaussNewton()

Set the region so large that it will select the Gauss-Newton point. This should should be a minimum for cost

computeStep_Hybrid

public void computeStep_Hybrid()

predict_cauchy

public void predict_cauchy()

predict_GaussNewton

public void predict_GaussNewton()

predict_Hybrid

public void predict_Hybrid()

cost

public static double cost(org.ejml.data.DenseMatrix64F residuals,
                          org.ejml.data.DenseMatrix64F J,
                          org.ejml.data.DenseMatrix64F h,
