Lightweight complex and hypercomplex algebra library.

Contents

  • Complex and hypercomplex numbers:
    • Complex<T> - 2-dimensional commutative and associative algebra.
    • Quaternion<T> - 4-dimensional associative but non-commutative algebra.
    • Octonion<T> - 8-dimensional non-commutative and non-associative algebra.
    • Sedenion<T> - 16-dimensional non-commutative and non-associative algebra with nontrivial zero divisors.
    • and following algebras created by Cayley-Dickson construction Construct<T, A<T>> where A<T> is previous algebra.
  • Transformations:
    • transform::Moebius<T, A<T>> - Moebius transform, where A<T> is some algebra.

To construct hypercomplex types from your own type you need to implement Algebra trait for it.

Crate Features

Crate could be used in no_std mode.

  • std - Use std. Enabled by default.
  • random - Hypercomplex number random generator.
  • approx - Approximate comparison of hypercomplex numbers.

Testing

cargo test --features random,approx
