Usage

diagnostics(x, ...)

Arguments

x: An eigencore result object.
...: Reserved for future methods.

Value

A named list of diagnostic fields, including residuals, backward errors, orthogonality diagnostics, iteration counts, method/plan metadata, warnings, and any available left-eigenvector diagnostics.

Examples

fit <- eig_partial(diag(c(3, 2, 1)), k = 1, target = largest())
d <- diagnostics(fit)
d$nconv
#> [1] 1
d$method
#> [1] "native dense Hermitian LAPACK fallback"
