Special matricesΒΆ
It is frequently useful to test algorithms on well-known, trivial, and random matrices, such as
matrices with entries sampled from a uniform distribution,
matrices with spectrum sampled from a uniform distribution,
Wilkinson matrices,
identity matrices,
matrices of all ones, and
matrices of all zeros.
Elemental therefore provides utilities for generating many such matrices.
