class Linear from Law inherits Function from Law
---Purpose: Describes an linear evolution law.

returns mutable Linear from Law;
---Purpose: Constructs an empty linear evolution law.
Set(me: mutable; Pdeb,Valdeb,Pfin,Valfin: Real from Standard)
---Purpose:
-- Defines this linear evolution law by assigning both:
-- - the bounds Pdeb and Pfin of the parameter, and
-- - the values Valdeb and Valfin of the function at these
-- two parametric bounds.

Value(me: mutable; X: Real from Standard)
returns Real from Standard;
---Purpose: Returns the value of this function at the point of parameter X.
D1(me: mutable; X: Real from Standard; F,D: out Real from Standard);
---Purpose:
-- Returns the value F and the first derivative D of this
-- function at the point of parameter X.
D2(me: mutable; X: Real from Standard;
F,D, D2: out Real from Standard);
---Purpose: Returns the value, first and second derivatives
-- at parameter X.
Trim(me; PFirst, PLast, Tol :Real from Standard) returns Function
---Purpose: Returns a law equivalent of <me> between
-- parameters <First> and <Last>. <Tol> is used to
-- test for 3d points confusion.
-- It is usfule to determines the derivatives
-- in these values <First> and <Last> if
-- the Law is not Cn.

---Purpose: Returns the parametric bounds of the function.
