Standard_Real | SearchOfTolerance () |
| Computes a Tol value. If 1st derivative of curve |D1|<Tol, it is considered D1=0.
|
|
virtual Standard_Boolean | Value (const Standard_Real X, Standard_Real &F)=0 |
| Computes the value <F>of the function for the variable <X>. Returns True if the calculation were successfully done, False otherwise.
|
|

|
virtual | ~math_Function () |
| Virtual destructor, for safe inheritance.
|
|
virtual Standard_Boolean | Value (const Standard_Real X, Standard_Real &F)=0 |
| Computes the value of the function <F> for a given value of variable <X>. returns True if the computation was done successfully, False otherwise.
|
|
virtual Standard_Integer | GetStateNumber () |
| returns the state of the function corresponding to the latest call of any methods associated with the function. This function is called by each of the algorithms described later which defined the function Integer Algorithm::StateNumber(). The algorithm has the responsibility to call this function when it has found a solution (i.e. a root or a minimum) and has to maintain the association between the solution found and this StateNumber. Byu default, this method returns 0 (which means for the algorithm: no state has been saved). It is the responsibility of the programmer to decide if he needs to save the current state of the function and to return an Integer that allows retrieval of the state.
