An abstract ndarray subclass over a Galois field or Galois ring.

Constructors¶

classmethod Identity(size: int, ...) → Self

Creates an $n\times n$ identity matrix.

classmethod Ones(shape: ShapeLike, ...) → Self

Creates an array of all ones.

classmethod Random(shape: ShapeLike = (), ...) → Self

Creates an array with random elements.

classmethod Range(start: ElementLike, stop, ...) → Self

Creates a 1-D array with a range of elements.

classmethod Zeros(shape: ShapeLike, ...) → Self

Creates an array of all zeros.

Methods¶

classmethod compile(mode)

Recompile the just-in-time compiled ufuncs for a new calculation mode.

classmethod repr(...) → Generator[None, None, None]

Sets the element representation for all arrays from this FieldArray subclass.
