======================================================== This is an advanced setting just for allowing increased choices to power users that have problems with a given sketch and want to test different flavours of DogLeg algorithm. This commit does not change the default behaviour of FreeCAD. It is only intended to give more options to power users. The advanced solver configuration is extended to support three different Gauss-newton steps for DogLeg: FullPivLU => h_gn = Jx.fullPivLu().solve(-fx); LeastNormFullPivLU => h_gn = Jx.adjoint()*(Jx*Jx.adjoint()).fullPivLu().solve(-fx); LeastNormLdlt => h_gn = Jx.adjoint()*(Jx*Jx.adjoint()).ldlt().solve(-fx); This setting is applied only to DogLeg. It is applied to DogLeg as normal or redundant solver, if DogLeg is the selected solver. Selecting a solver different from DogLeg for both normal and redundant disables the setting. We have been told: https://forum.kde.org/viewtopic.php?f=74&t=129439#p346104 that our default Gauss-Newton step in DogLeg may not be adequate in general (we generally deal with underconstraint systems unless we have a fully constraint sketch, and even then it is many times overconstraint at least for redundant solving). We have been told that maybe these LeastNorm options are more suitable for us (performance set aside). This enables you as power user to test if it works fine with FreeCAD.
