8.2.11 Metrics and R  conversion

T width() const; 
T midpoint() const; 
T magnitude() const; 
T mignitude() const; 
T pivot() const; 
T size() const; 
T radius() const;

These functions convert the triplex into a R  space representation. Given the current triplex as A ∈ TR  these metrics are defined as:

width()


Width of the triplex a-a- .

midpoint()


Midpoint of the triplex 1(a+ a)
2.

magnitude()


Magnitude of the triplex max(|a|,| a|)  .

mignitude()


Mignitude of the triplex min(|a|,| a|)  .

pivot()


Pivot of the triplex √︁max(-|a|,| a|)min(|a|,| a|)  .

size()


Size of the triplex 1(|a-|+ |a|)
2.

radius()


Radius of the triplex     (-        -  )
max  a-a-a,a--a-a
      2        2.
