NumPy to C++14: the xtensor cheat sheet

What it does

Two container types are provided. xt::xarray (dynamic number of dimensions) and xt::xtensor (static number of dimensions). Lazy helper functions return tensor expressions. Return types don’t hold any value and are evaluated upon access or assignment. They can be assigned to a container or directly used in expressions. xtensor’s meshgrid implementation corresponds to numpy’s 'ij' indexing order. xtensor offers lazy numpy-style broadcasting, and universal functions. Unlike numpy, no copy or temporary variables are created. The random module provides simple ways to create random tensor expressions, lazily. See numpy.random and xtensor random page. Concatenating expressions does not allocate…from xtensor.readthedocs.io
