Function nalgebra::linalg::wilkinson_shift

source · 
pub fn wilkinson_shift<T: ComplexField>(tmm: T, tnn: T, tmn: T) -> T
Expand description

Computes the wilkinson shift, i.e., the 2x2 symmetric matrix eigenvalue to its tailing component tnn.

The inputs are interpreted as the 2x2 matrix: tmm tmn tmn tnn
