solve.eigencore_eigen_problem: Solve a planned eigenproblem.

In eigencore: Certified Partial Eigenvalue and Singular Value Computation

Solve a planned eigenproblem.

Description

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.
