class RuledInv from BlendFunc

	---Purpose: 

inherits FuncInv from Blend


uses Vector from math,
     Matrix from math,
     HCurve2d from Adaptor2d,
     HCurve from Adaptor3d,
     HSurface from Adaptor3d

    	returns RuledInv from BlendFunc;

    IsSolution(me: in out; Sol: Vector from math; Tol: Real from Standard)
    
    	returns Boolean from Standard

    NbEquations(me)
    	---Purpose: returns the number of equations of the function.
    	returns Integer from Standard
    	 is redefined static   ;

    Value(me: in out; X: Vector; F: out Vector)
    	---Purpose: computes the values <F> of the Functions for the 
    	--          variable <X>.
    	--          Returns True if the computation was done successfully, 
    	--          False otherwise.

    	---Purpose: returns the values <D> of the derivatives for the 
    	--          variable <X>.
    	--          Returns True if the computation was done successfully, 
    	--          False otherwise.

    returns Boolean from Standard

    Values(me: in out; X: Vector; F: out Vector; D: out Matrix)
    	---Purpose: returns the values <F> of the functions and the derivatives
    	--          <D> for the variable <X>.
    	--          Returns True if the computation was done successfully,
