AD<double> not working in Eigen with some complex function #156

Closed nixwang closed 1 year ago

nixwang commented 2 years ago

Hello, i'm here again for any help. AD not working in Eigen with some complex function, like Eigen::EigenSolver.pseudoEigenvalueMatrix or pseudoEigenvectors, or Eigen::LDLT.solve. Is there any suggestion, please. Thanks a lot

Can you provide a short example, with as small a matrix as possible, that demonstrates the problem ?

nixwang commented 2 years ago

Sorry, the function is in a complex project, it need some time to extract a short example. Thanks for your reply.

Sometimes when I think there is a problem with a package, and I try to create a simple example demonstrating the problem, I realize that it was a mistake in my use of the package or a mistake in code that is not connected to the package.

@nixwang Is this still an issue for you ?
