RSpectra-compatible SVD shim.

Usage

svds(A, k, nu = k, nv = k, opts = list(), ...)

Arguments

A: Matrix or eigencore operator.
k: Number of singular values to compute.
nu: Number of left singular vectors requested.
nv: Number of right singular vectors requested.
opts: Compatibility options list; currently accepted for API compatibility and not interpreted directly.
...: Additional arguments passed to svd_partial().

Value

A list compatible with RSpectra::svds(), including d, optional u and v, convergence counts, operation counts, certificate diagnostics, and eigencore diagnostics.

Examples

set.seed(1)
X <- matrix(rnorm(60), 10, 6)
res <- svds(X, k = 2)
res$d
