Struct EigshWorkspace 

pub struct EigshWorkspace { /* private fields */ }

Reusable state for a sequence of related Hermitian eigenproblems.

The workspace keeps the complete converged invariant subspace from the previous solve. eigsh_with_workspace preserves it as a thick initial subspace for restarted windows and combines all of its vectors into a balanced warm start when the cheaper tridiagonal Lanczos path applies.

Implementations

impl EigshWorkspace

pub const fn new() -> Self

Create an empty workspace that accepts the first solved dimension.

pub fn clear(&mut self)

Forget the stored dimension and converged invariant subspace.

pub const fn dimension(&self) -> usize

Return the operator dimension associated with the stored subspace.

pub fn initial_subspace(&self) -> &[Vec<Complex64>]

Borrow the complete converged subspace from the previous solve.

pub fn set_initial_subspace( &mut self, dimension: usize, vectors: impl IntoIterator<Item = Vec<Complex64>>, ) -> Result<()>

Install a user-provided warm-start subspace after validating dimensions.
