Method Details

__new__ (cls, sa, ca, sb, cb, *_more)
Static Method

 

New EcefMatrix matrix.

Arguments:
  • sa - sin(phi) (float).
  • ca - cos(phi) (float).
  • sb - sin(lambda) (float).
  • cb - cos(lambda) (float).
  • _more - (INTERNAL) from .multiply.
Returns: a new object with type S, a subtype of T
Raises:
  • EcefError - If sa, ca, sb or cb outside [-1.0, +1.0].
Overrides: object.__new__

copy (self, **unused)

 

Make a shallow or deep copy of this instance.

Arguments:
  • deep - If True, make a deep, otherwise a shallow copy (bool).
  • name - Optional, non-empty name=NN (str).
Returns:
The copy (This class or subclass thereof).
Overrides: named._Named.copy

__deepcopy__ (self, **unused)

 

Make a shallow or deep copy of this instance.

Arguments:
  • deep - If True, make a deep, otherwise a shallow copy (bool).
  • name - Optional, non-empty name=NN (str).
Returns:
The copy (This class or subclass thereof).

__copy__ (self, **unused)

 

Make a shallow or deep copy of this instance.

Arguments:
  • deep - If True, make a deep, otherwise a shallow copy (bool).
  • name - Optional, non-empty name=NN (str).
Returns:
The copy (This class or subclass thereof).

multiply (self, other)

 

Matrix multiply M0' ⋅ M this matrix Transposed with an other matrix.

Arguments:
Returns:
The matrix product (EcefMatrix).
Raises:

rotate (self, xyz, *xyz0)

 

Forward rotation M0' ⋅ ([x, y, z] - [x0, y0, z0])'.

Arguments:
  • xyz - Local (x, y, z) coordinates (3-tuple).
  • xyz0 - Optional, local (x0, y0, z0) origin (3-tuple).
Returns:
Rotated (x, y, z) location (3-tuple).
Raises:
  • LenError - Unequal len(xyz) and len(xyz0).

unrotate (self, xyz, *xyz0)

 

Inverse rotation [x0, y0, z0] + M0 ⋅ [x,y,z]'.

Arguments:
  • xyz - Local (x, y, z) coordinates (3-tuple).
  • xyz0 - Optional, local (x0, y0, z0) origin (3-tuple).
Returns:
Unrotated (x, y, z) location (3-tuple).
Raises:
  • LenError - Unequal len(xyz) and len(xyz0).
