v0.0.31¶

Released July 24, 2022

Breaking changes¶

• Renamed FieldArray.Elements() classmethod to FieldArray.elements class property. This naming convention is more consistent with primitive_elements, units, quadratic_residues, and quadratic_non_residues. (#373)

  >>> GF = galois.GF(3**2, display="poly")
  >>> GF.elements
  GF([     0,      1,      2,      α,  α + 1,  α + 2,     2α, 2α + 1,
      2α + 2], order=3^2)
  

• Renamed BCH.systematic to BCH.is_systematic. (#376)

• Renamed ReedSolomon.systematic to ReedSolomon.is_systematic. (#376)

Changes¶

• Added support for polynomial composition in Poly.__call__(). (#377)

  >>> GF = galois.GF(3**5)
  >>> f = galois.Poly([37, 123, 0, 201], field=GF); f
  Poly(37x^3 + 123x^2 + 201, GF(3^5))
  >>> g = galois.Poly([55, 0, 1], field=GF); g
  Poly(55x^2 + 1, GF(3^5))
  >>> f(g)
  Poly(77x^6 + 5x^4 + 104x^2 + 1, GF(3^5))
  

• Added FieldArray.units class property. (#373)

  >>> GF = galois.GF(3**2, display="poly")
  >>> GF.units
  GF([     1,      2,      α,  α + 1,  α + 2,     2α, 2α + 1, 2α + 2],
     order=3^2)
  

Documentation¶

• Reworked API reference using Sphinx Immaterial’s python-apigen. (#370)

• Shortened website URLs to use directories. https://galois.readthedocs.io/en/v0.0.30/getting-started.html is converted to https://galois.readthedocs.io/en/v0.0.31/getting-started/. (#370)
