Classes for norms based on quadratic forms

could be created by a call to `new`

, but
normally one would use the generating functions `QFNorm`

,
`InfoNorm`

, and `SelfNorm`

`name`

Object of class

`"character"`

.`fct`

Object of class

`"function"`

.`QuadForm`

Object of class

`"PosSemDefSymmMatrix"`

.

`"QFNorm"`

extends class `"NormType"`

, directly,
and `"InfoNorm"`

and `"SelfNorm"`

each extend
class `"QFNorm"`

, directly (and do not have extra slots).

- QuadForm
`signature(object = "QFNorm")`

: accessor function for slot`QuadForm`

.- QuadForm<-
`signature(object = "QFNorm")`

: replacement function for slot`QuadForm`
