29.7.4.1 Class slice 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;
  };
}
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.281
BLAS stands for Basic Linear Algebra Subprograms. C++ programs may instantiate this class.
