Function heron::rapier_plugin::rapier::parry::na::wilkinson_shift [−][src]
pub fn wilkinson_shift<T>(tmm: T, tnn: T, tmn: T) -> T where
T: ComplexField,
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
