Detailed Description

template<uni20::Real Real>
struct uni20::krylov::symmetric_tridiagonal_view< Real >

Non-owning read-only view of a real symmetric tridiagonal matrix.

Template Parameters

Real	Real floating-point scalar type.

The matrix is represented by its diagonal d[0..n) and offdiagonal e[0..n-1), where e[i] is both element (i, i + 1) and (i + 1, i). This is the natural projected matrix format produced by Hermitian Lanczos, including complex-Hermitian problems, whose Lanczos projection is real symmetric tridiagonal.
