Web6. feb 2024 · A span provides a safe way to iterate over and index into objects that are arranged back-to-back in memory. Such as objects stored in a built-in array, std::array, or std::vector. If you typically access a sequence of back-to-back objects using a pointer and an index, a span is a safer, lightweight alternative. WebA span is the result of taking all possible linear combinations of some set of vectors (often this set is a basis). Put another way, a span is an entire vector space while a basis is, in a sense, the smallest way of describing that space using some of its vectors. How many vectors are in a span?
