class ElementsOfRefMatrix from FEmTool inherits FunctionSet from math
|
|
|
|
---Purpose: this class describes the functions needed for
|
|
-- calculating matrix elements of RefMatrix for linear
|
|
-- criteriums (Tension, Flexsion and Jerk).
|
|
-- 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.

|
|
---Purpose: returns the number of equations of the function.
|

Value(me: in out; X: Vector; F: out Vector)
|
|
---Purpose: computes the values <F> of the functions for the

|
|
-- returns True if the computation was done successfully,
|
|
-- False otherwise.
|
|
-- F contains results only for i<=j in following order:
