Re: [eigen] Block sparse matrices and std vector compilation error

Hi Christoph,

The goal of using the sub matrices is to fill the larger matrix in parallel in order to use a sparse optimizer once the matrix has been configured. Thanks for the proxy suggestion, it’s what I am currently implementing.

I added a bz entry for that. I guess this won't make it to 3.3, but perhaps 3.4 is realistic:
