Here is a list of all topics with brief descriptions:

Adaptors of STL-like containers
Xt_xchunked_array	Chunked array container
Xt_xcomplex	Defined in `xtensor/xcomplex.hpp`
Xt_xeval	Evaluation functions
Xt_xfunctor_view	Chunked array container
Xt_xmanipulation
Basic functions
Exponential functions
Power functions
Trigonometric function
Hyperbolic functions
Error and gamma functions
Nearest integer floating point operations
Classification functions
reducing functions
accumulating functions
nan functions
Arithmetic operators
Logical operators
Bitwise operators
Comparison operators
Casting operators
Support functions to get/check a shape array.
Sorting functions.	Because sorting functions need to access the tensor data repeatedly, they evaluate their input and may allocate temporaries
Support functions swich between array indices and flat indices
