Source: R/methods-sparse.R
eigen-sparse-methods.Rd

Compute eigenvalues and eigenvectors of a sparse adgCMatrix, dispatching through the amatrix backend.

Usage

# S4 method for class 'adgCMatrix'
eigen(x, symmetric, only.values = FALSE, EISPACK = FALSE)

Arguments

x

An adgCMatrix.

symmetric

Logical; whether x is symmetric. Auto-detected when missing.

only.values

Logical; if TRUE only eigenvalues are returned.

EISPACK

Ignored; retained for signature compatibility.

Value

A list with components values and vectors.
