BRepApprox_ResConstraintOfMyGradientOfTheComputeLineBezierOfApprox (const BRepApprox_TheMultiLineOfApprox &SSP, AppParCurves_MultiCurve &SCurv, const Standard_Integer FirstPoint, const Standard_Integer LastPoint, const Handle< AppParCurves_HArray1OfConstraintCouple > &Constraints, const math_Matrix &Bern, const math_Matrix &DerivativeBern, const Standard_Real Tolerance=1.0e-10)
Given a MultiLine SSP with constraints points, this algorithm finds the best curve solution to approximate it. The poles from SCurv issued for example from the least squares are used as a guess solution for the uzawa algorithm. The tolerance used in the Uzawa algorithms is Tolerance. A is the Bernstein matrix associated to the MultiLine and DA is the derivative bernstein matrix.(They can come from an approximation with ParLeastSquare.) The MultiCurve is modified. New MultiPoles are given. More...
