„alpha“ befindet sich nicht in der Liste (experimental, beta, stable, obsolete, unknown) zulässiger Werte für das Attribut „Pr status“.




LibBracket ist ein Framework zum Bau von algebraischen Termumformern eines bestimmten Musters.

Beispiel

 require 'libbracket'
 
 module Scalars
   include LibBracket::IsSummable
   include LibBracket::IsMultipliable
 end
 
 module Other
   include LibBracket::IsSummable
   include LibBracket::HasScalarsFromLeft
   include LibBracket::ScalarMultipleOperator
   
   include LibBracket::HasInnerProduct
   domain_of_inner_product Scalars
 end
 
 f = LibBracket::Atom.from_domain_and_name Scalars, "f"
 
 A = LibBracket::Atom.from_domain_and_name Other, "A"
 B = LibBracket::Atom.from_domain_and_name Other, "B"
 C = LibBracket::Atom.from_domain_and_name Other, "C"
 
 term = C.inner_product_with(A + Other::ZERO + B*f)
 
 puts term.to_s # => <C, (A + 0) + f*B>
 
 term2 = term.canonicalize_and_replace
 
 puts term2.to_s # => <A, C> + f*<B, C>
