Eigen - Levenberg Marquardt algorithm: invalid template arguments on definition of permutation

阅读更多关于 Eigen - Levenberg Marquardt algorithm: invalid template arguments on definition of permutation

问题 I'm trying to use the Eigen implementation of Levenberg Marquardt algorithm on a Android application. In order to use Eigen, I'm using Android NDK and jni. I've already tested Eigen with simple calculations (like matrix creation and vector sums) and it works perfectly. However, when I tried to use the Levenberg Marquardt algorithm I got some errors on the LevenbergMarquardt.h file from Eigen's library. First, here is my code. I based on this code: Eigen::MatrixXd matrix(count, 3); for (int i

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . I'm looking for a library in C that will do optimization of an objective function (preferrably Levenberg-Marquardt algorithm) and will support box constraints, linear inequality constraints and non-linear inequality constraints. I've tried several libraries already, but none of them do employ the necessary

问题 We want to implement some kind of indoor position determination using iBeacons. This article seems really interesting, in which the author implemented the Non-linear Least Squares Triangulation, using the Eigen C++ library and the Levenberg Marquardt algorithm. Since Eigen is written in C++, I tried to use JNI and Android NDK in order to use it but it throws a lot of errors that I have no idea how to solve and I couldn´t find anything online. I also tried to use Jeigen, but it does not have

I'm looking for a library in C that will do optimization of an objective function (preferrably Levenberg-Marquardt algorithm) and will support box constraints, linear inequality constraints and non-linear inequality constraints. I've tried several libraries already, but none of them do employ the necessary constraint types for my application: GNU GSL (does not support constraints at all) cMPFIT (only supports box constraints) levmar (does not support non-linear constraints at all) I am currently exploring NLopt , but I'm not sure if I can achieve a least-squares approach with any of the
