C++ tensors with broadcasting and lazy computing
Assigning on axis_slice_range (and axis_range) does not work as expected, unless the range is contiguous in memory. The code ```cpp xt::xarray data = xt::empty({2,3}); float test = 2.0f; for (auto...

I'm wondering if there is an easy way to select specific columns (or rows, tubes, etc.) using a boolean mask. In matlab it looks like ``` Z = rand(N,K) >...
This issue tracks the benefits of migrating the codebase to C++17, and its consequences. First we would have to drop the support for the following compilers: - gcc 4.9, 5,...
Currently, `xt::concatenate` takes `xt::tuple` as its first argument which means that the number of input arrays to `xt::concatenate` has to be specified during the compile time. Would it be possible...
## code ```c++ xt::xarray a = {{1, 5, 3}, {4, 5, 6}}; xt::xarray mask = {{true, false, false}, {false, true, false}}; auto m = xt::masked_view(a, mask); // => m =...
It might be worth to have set of tests for which we use the preprocessor to run them on xarray, xtensor, xtensor_fixed, pyarray, pytensor, ... This should reveal minor issues...
Has the time come that we should make the change `master` -> `main`? It's starting to become one a few projects I participate on that is still on `master`
In c++20 `std::allocator::reference` was removed, but the `xt::tracking_allocator` uses it with `using reference = typename A::reference;` which results in error: ```cpp .../xtensor/xutils.hpp:731:39: error: no type named 'reference' in 'std::allocator' using...
