Implements type conversion to complex. Truncates the Quaternion object by only considering the real component and the first imaginary

Returns true if the following is true for each element: `absolute(a - b) <= (atol + rtol * absolute(b))`

Implements type conversion to float. Truncates the Quaternion object by only considering the real component.

Inserts a customisable, nicely printable string representation of the Quaternion object The syntax for `format_spec` mirrors that of the buil

Initialise a new Quaternion object. See Object Initialisation docs for complete behaviour: http://kieranwynn.github.io/pyquaternion/

Implements type conversion to int. Truncates the Quaternion object by only considering the real component and rounding to the next in

The 'official' string representation of the Quaternion object. This is a string representation of a valid Python expression that could be use

An informal, nicely printable string representation of the Quaternion object.

Quaternion absolute distance. Find the distance between two quaternions accounting for the sign ambiguity. Params: q0: t

Get the angle (in radians) describing the magnitude of the quaternion rotation about its rotation axis. This is guaranteed to be within the r

Quaternion conjugate, encapsulated in a new instance. For a unit quaternion, this is the same as the inverse. Returns: A

Method supposedly able to deal with non-orthogonal matrices - NON-FUNCTIONAL! Based on this method: http://arc.aiaa.org/doi/abs/10.2514/2

Get the instantaneous quaternion derivative representing a quaternion rotating at a 3D rate vector `rate` Params: rate: numpy 3-a

Quaternion intrinsic distance. Find the intrinsic geodesic distance between q0 and q1. Params: q0: the first quaternion

Return all the elements of the quaternion object. Returns: A numpy 4-array of floats. NOT guaranteed to be a unit vector

Convert Euler angles to quaternions.

Quaternion exponential map. Find the exponential map on the Riemannian manifold described by the quaternion space. Params:
