Algebra.ModuleBasis

Contents

Description

Abstraction of bases of finite dimensional modules

Synopsis

Documentation

class C a v => C a v where Source #

It must hold:

  Module.linearComb (flatten v `asTypeOf` [a]) (basis a) == v
  dimension a v == length (flatten v `asTypeOf` [a])

Minimal complete definition

basis, flatten, dimension

Methods

basis :: a -> [v] Source #

basis of the module with respect to the scalar type, the result must be independent of argument, undefined should suffice.

flatten :: v -> [a] Source #

scale a vector by a scalar

dimension :: a -> v -> Int Source #

the size of the basis, should also work for undefined argument, the result must be independent of argument, undefined should suffice.
