Methods

impl EigenGenSymmVWorkspace

fn new(n: usize) -> Option<EigenGenSymmVWorkspace>

This function allocates a workspace for computing eigenvalues and eigenvectors of n-by-n real generalized symmetric-definite eigensystems. The size of the workspace is O(4n).

fn gensymmv(
    &mut self,
    A: MatrixF64,
    B: &mut MatrixF64,
    eval: &mut VectorF64,
    evec: &mut MatrixF64
) -> Value

This function computes the eigenvalues and eigenvectors of the real generalized symmetric-definite matrix pair (A, B), and stores them in eval and evec respectively. The computed eigenvectors are normalized to have unit magnitude. On output, B contains its Cholesky decomposition and A is destroyed.
