Re: [eigen] LevenbergMarquardt VC2008 error

[Thomas Capricelli <orzel@xxxxxxxxxxxxxxx>]

Err..!! ?? No, i'm afraid i can not. Benoit, Gael.. any idea ? The code leading to this is unsupported/Eigen/src/NonLinearOptimization/lmpar.h:218 :

qr.matrixQR().topLeftCorner(n, n).transpose().template triangularView<Lower>().solveInPlace(wa1);

I guess some recent changes about correctness is responsible for this.. ? Should i use some newer API ? I can't reproduce here, the unittests for LevenbergMarquardt in eigen compiles fine here, and my own projects based on eigen that uses LM have no compilation problem either...
