| LinearTransform1D | | protected LinearTransform1D(double scale, double offset)(Code) | | Constructs a new linear transform. This constructor is provided for subclasses only.
Instances should be created using the
, which
may returns optimized implementations for some particular argument values.
Parameters:
scale - The scale term in the linear equation.
Parameters:
offset - The offset term in the linear equation. |
| create | | public static LinearTransform1D create(double scale, double offset)(Code) | | Constructs a new linear transform.
Parameters:
scale - The scale term in the linear equation.
Parameters:
offset - The offset term in the linear equation. |

from the default
AbstractMathTransform.derivative implementation in that no
coordinate point is required and
Double.NaN may be a legal output value for
some users.
|
| derivative | | public double derivative(double value)(Code) | | Gets the derivative of this function at a value.
|
| equals | | public boolean equals(Object object)(Code) | | Compares the specified object with this math transform for equality.
