FEmTool_ElementsOfRefMatrix Class Reference

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.

 FEmTool_ElementsOfRefMatrix (const Handle< PLib_Base > &TheBase, const Standard_Integer DerOrder)
Standard_Integer NbVariables () const
 returns the number of variables of the function.
It is supposed that NbVariables = 1.

Standard_Integer NbEquations () const
 returns the number of equations of the function.

Standard_Boolean Value (const math_Vector &X, math_Vector &F)
 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})
