this class describes the functions needed for calculating matrix elements of RefMatrix for linear criteriums (Tension, Flexion and Jerk) by Gauss integration. Each function from set gives value Pi(u)'*Pj(u)' or Pi(u)''*Pj(u)'' or Pi(u)'''*Pj(u)''' for each i and j, where Pi(u) is i-th basis function of expansion and (') means derivative. More...

| bool | Value (const math_Vector &X, math_Vector &F) override |
| computes the values <F> of the functions for the variable <X>. returns True if the computation was done successfully, False otherwise. F contains results only for i<=j in following order: P0*P0, P0*P1, P0*P2... P1*P1, P1*P2,... (upper triangle of matrix {PiPj}) | |

| virtual int | GetStateNumber () |
| Returns the state of the function corresponding to the latestcall of any methods associated with the function. This function is called by each of the algorithms described later which define 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. | |
