Provide lightweight class for pointer to external data

[tdegeus]

API

It would be great to be able to do

std::vector<double> data(size);
xt::tensor_pointer<double, 2> a(data, shape);

and then do normal operations with a. An advantage is that a could also for example be a member variable.

Implementation

Such a classes could be aliases for

xarray_adaptor<xbuffer_adaptor<...>, ...>
xtensor_adaptor<xbuffer_adaptor<...>, ...>

see

xtensor/include/xtensor/xadapt.hpp

Line 101 in a57a6fa

using return_type = xarray_adaptor<buffer_type, L, std::decay_t<SC>>;
