Solve a planned eigenproblem. — solve.eigencore_eigen

S3 method that runs the planned solver for an eigenproblem built by eigen_problem(). Most users call eig_partial(), which constructs the problem and dispatches here; call solve() directly when you want to build a problem once and reuse or inspect it. Returns a certified partial eigendecomposition.

Usage

# S3 method for class 'eigencore_eigen_problem'
solve(
  a,
  b,
  k,
  method = auto(),
  tol = 1e-08,
  maxit = NULL,
  vectors = TRUE,
  certify = TRUE,
  allow_dense_fallback = c("auto", "never", "always"),
  ...
)

Arguments

a: Eigencore eigen problem object.
b: Unused second argument reserved by the base solve() generic.
k: Number of eigenpairs to compute.
method: Solver method descriptor.
tol: Convergence and certification tolerance.
maxit: Optional iteration limit.
vectors: Whether to compute vectors.
certify: Whether to compute certification diagnostics.
allow_dense_fallback: Dense fallback policy.
...: Reserved for future solver options.

Value

An eigencore_eigen_result.
