Detailed Description

template<uni20::Real Real>
class uni20::krylov::symmetric_tridiagonal_matrix< Real >

Fixed-size owning real symmetric tridiagonal matrix.

Template Parameters

Real	Real floating-point scalar type.

The public spans are const handles into the owned storage: callers may mutate entries through diagonal[i] and offdiagonal[i], but cannot rebind the handles or resize the matrix. Use external vectors and symmetric_tridiagonal_view directly when resizable Lanczos state is needed.
