Interface Formula

public interface Formula

Specification of the coordinate operation method formula. A formula may be given textually, or may be a reference to a publication. If the operation method is not analytic, then Formula actually gives the procedure rather than an analytic formula.

Formulas are given by OperationMethod.getFormula(). Formula objects are for human reading; the object that actually does the work of applying the formula or procedure to coordinate values is MathTransform.

Since:
