deferred class ElementaryCriterion from FEmTool inherits TShared from MMgt
---Purpose: defined J Criteria to used in minimisation
uses
Vector from math,
Matrix from math,
HArray2OfReal from TColStd,
HArray2OfInteger from TColStd
raises
NotImplemented,
DomainError
is
Set(me : mutable;
Coeff : HArray2OfReal)
---Purpose: Set the coefficient of the Element (the Curve)
is static;
Set(me : mutable;
FirstKnot : Real;
LastKnot : Real)
---Purpose: Set the definition interval of the Element
is virtual;
DependenceTable(me)
returns HArray2OfInteger from TColStd
---Purpose: To know if two dimension are independent.

---Purpose: To Compute J(E) where E is the current Element
returns Real is deferred;

H : out Matrix from math)
---Purpose: To Compute J(E) the coefficients of Hessian matrix of
