treams._core.PhysicsArray

class treams._core.PhysicsArray(arr, ann=(), /, **kwargs)

Physics-aware array.

A physics aware array is a special type of :class`treams.util.AnnotatedArray`. Additionally to keeping track of the annotations, it is enhanced by the ability to create suiting linear operators to perform tasks like rotations, translations, or expansions into different basis sets and by applying special rules for the physical properties of PhysicsDict upon matrix multiplications, see also __matmul__().

__init__(arr, ann=(), /, **kwargs)

Initialization.

Methods

__init__(arr[, ann])	Initialization.
all([axis, dtype, out, keepdims, where])	Test if all elements (along an axis) are True.
any([axis, dtype, out, keepdims, where])	Test if any element (along an axis) is True.
astype(*args, **kwargs)	Return array as given type.
conj(*args, **kwargs)	Complex conjugate elementwise.
conjugate(*args, **kwargs)	Complex conjugate elementwise.
cumprod([axis, dtype, out])	Cumulative product of elements (along an axis).
cumsum([axis, dtype, out])	Cumulative sum of elements (along an axis).
diagonal([offset, axis1, axis2])	Get the diagonal of the array.
flatten([order])	Flatten array to one dimension.
max([axis, out, keepdims, initial, where])	Maximum (along an axis).
min([axis, out, keepdims, initial, where])	Minimum (along an axis).
prod([axis, dtype, out, keepdims, initial, ...])	Product of elements (along an axis).
