Selecting specific rows of 2D xtensor

How to convert an xarray to std::vector?

QUESTION

Selecting specific rows of 2D xtensor

Asked 2020-Apr-30 at 08:52

xtensor's documentation provides a map to numpy's functionalities (link).

The list covers many use cases but there is one functionality I couldn't recreate. I have a 2D tensor and I want to select specific rows which are identified by a sequence that is built at run time. My understanding is this prevents the use of xt::drop and xt::keep since those are variadic template functions (I've just begun learning c++ so correct me if I'm missing something). Also, that sequence is irregular and cannot be replicated by xt::range.

Here's something along the lines of what I want in numpy:
