Struct rgsl::types::eigen_symmetric_workspace::EigenGenSymmVWorkspace

pub struct EigenGenSymmVWorkspace { /* private fields */ }

Implementations

impl EigenGenSymmVWorkspace

pub fn new(n: usize) -> Option<Self>

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).

pub fn gensymmv( &mut self, A: MatrixF64, B: &mut MatrixF64, eval: &mut VectorF64, evec: &mut MatrixF64 ) -> Result<(), 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.

Trait Implementations

impl Drop for EigenGenSymmVWorkspace
