nifty8.domains.dof_space module#

class DOFSpace(dof_weights)[source]#

Bases: StructuredDomain

Generic degree-of-freedom space. It is defined as the domain of some DOFDistributor. Its entries represent the underlying degrees of freedom of some other space, according to the dofdex.

Parameters:: dof_weights (1-D numpy array) – A numpy array containing the multiplicity of each individual degree of freedom.

__init__(dof_weights)[source]#

__repr__()[source]#: Return repr(self).

property dvol#

pixel volume(s)

Returns the volume factors of this domain, either as a floating point scalar (if the volume factors are all identical) or as a floating point array with a shape of self.shape.

Type:: float or numpy.ndarray(dtype=float)

property harmonic#

True iff this domain is a harmonic domain.

Type:: bool

property scalar_dvol#

uniform pixel volume, if applicable

Returns the volume factors of this domain as a floating point scalar, if the volume factors are all identical, otherwise returns None.

Type:: float or None

property shape#

number of pixels along each axis

The shape of the array-like object required to store information defined on the domain.

Type:: tuple of int

property size#

total number of pixels.

Equivalent to the products over all entries in the domain’s shape.

Type:: int
