from_polar#
- classmethod ReciprocalLatticeVector.from_polar(azimuth, polar, radial=1)[source]#
Initialize from spherical coordinates according to the ISO 31-11 standard :cite:`weisstein2005spherical`.
- Parameters:
azimuth – Azimuth angle(s) in radians (
degrees=False
) or degrees (degrees=True
).polar – Polar angle(s) in radians (
degrees=False
) or degrees (degrees=True
).radial – Radial distance. Defaults to 1 to produce unit vectors.
degrees – If
True
, the angles are assumed to be in degrees. Default isFalse
.
- Return type:
