Hey Eigen community,
I was trying to write a function taking in any eigen expression which has
direct memory access. That is I am looking for the expression type which
has access to a memory location and associated size and stride information.
I think the correct type for this should be Eigen::DenseCoeffsBase<Derived,
Eigen::DirectWriteAccess>. Am I right in assuming so? Unfortunately casting
an derived type into this expression is resulting dangling references, see
e.g https://godbolt.org/z/KPdcoG. Can someone point me out what I am doing
wrong?
cheers
