Detailed Description

template<typename Precision>
struct TooN::ILinear< Precision >

A reweighting class representing no reweighting in IRLS.

$w(x)=1$ This structure can be passed as the second template argument in IRLS.


Member Function Documentation

void set_sd ( Precision   ) 

Set the noise standard deviation (does nothing).

Precision reweight ( Precision  d  ) 

Returns $w(x)$.

Precision true_scale ( Precision  d  ) 

Returns $w(x) + xw'(x)$.

Precision objective ( Precision  d  ) 

Returns $\int xw(x)dx$.
