26.7.4.1 Overview [class.slice.overview]

namespace std { class slice { public: slice(); slice(size_t, size_t, size_t); size_t start() const; size_t size() const; size_t stride() const; friend bool operator==(const slice& x, const slice& y); }; }
The slice class represents a BLAS-like slice from an array.
Such a slice is specified by a starting index, a length, and a stride.249

BLAS stands for Basic Linear Algebra Subprograms.
C++ programs can instantiate this class.
