public AbstractDifferentiableRealTransform()
```
- Method Detail
  - jacobian
```
public abstract AffineTransform jacobian(double[] x)
```
    Returns the jacobian matrix of this transform at the point x.
    
    Specified by:
    
    jacobian in interface DifferentiableRealTransform
    
    Parameters:
    
    x - the point
    
    Returns:
    
    the jacobian
  - directionToward
```
public void directionToward(double[] displacement,
                            double[] x,
                            double[] y)

    Writes the direction displacement in which to move the input source point x in order that F( x + d ) is closer to the destination point y than F( x ).
    The output is a normalized vector.
    
    Specified by:
    
    directionToward in interface DifferentiableRealTransform
    
    Parameters:
    
    displacement - the displacement to write into
    
    x - the source point
    
    y - the destination point
  - directionToward
```
public static void directionToward(AffineTransform jacobian,
                                   double[] displacement,
                                   double[] x,
