conditionLimit
The condition number limit (Fong-Saunders test only).
Declaration
var conditionLimit: DoubleDiscussion
The operation terminates iterations if a computed estimate of cond(Abar) exceeds this value. This is to prevent certain small or zero singular values of A or Abar from coming into effect and causing unwanted growth in the computed solution.
You can use conditionLimit and lambda separately or together to regularize ill-conditioned systems.
Normally, conditionLimit is in the range 1000 to 1/eps.
Suggested value: conditionLimit = 1/(100*eps) for compatible systems, conditionLimit = 1/(10*sqrt(eps)) for least squares
