Good day and thanks for your work. I'm trying to run the demo2.py to get the rotating 3d image, and the image window does appear with the axes, but no...

The docstring for yaw_pitch_rolls states as follows: """Get the equivalent yaw-pitch-roll angles aka. intrinsic Tait-Bryan angles following the z-y'-x'' convention Returns: yaw: rotation angle around the z-axis in radians, in...

Hi, hope you will find these changes useful/helpful. I'm looking for a speedup of pyquaternion code, primarily targeting numba jit compiler. I've added basic support for numba into pyquaternion, as...

Matrix to quaternion

I found a possible conversion bug that caused by [this line](https://github.com/KieranWynn/pyquaternion/blob/master/pyquaternion/quaternion.py#L217). Should the w(real) be `M[0, 2]-M[2, 0]`? I use [this website](https://www.andre-gaschler.com/rotationconverter/) for verification. ``` [ -0.4285714, 0.2857143, 0.8571429; 0.8571429,...

Would be nice if this there was a conda distribution on conda-forge.

Resolves https://github.com/KieranWynn/pyquaternion/issues/39 Remove as many calls as possible to `Quaternion._normalise()` and `Quaternion._fast_normalise()` as these mutate the object and cause implicit side effects. Updated docs to encourage the use of `Quaternion.normalised`...

test_init_from_explicit_matrix_with_optional_tolerance_arguments fails complaining that the matrix is not orthogonal within tolerance 1e-07. When I compute the dot of the matrix and its transpose using numpy I get: ``` [[ 1.00585937,...

Hi, I'm having unexpected behavior that could just be me misusing the library, or could be a problem with the library itself. Either way, I'd greatly appreciate if someone could...
