mgen 1.2.1

Trivial example usage

Below you see examples of how to use mgen to generate rotation matrices. For further documentation please have a look here: https://mgen.readthedocs.io

import numpy as np
np.set_printoptions(suppress=True)

from mgen import rotation_around_axis
from mgen import rotation_from_angles
from mgen import rotation_around_x
from mgen import rotation_from_angle_and_plane
from mgen import rotation_from_angle
from mgen import random_matrix

# 2D example
matrix = rotation_from_angle(np.pi/2)
matrix.dot([1, 0])
# array([0., 1.])

#3D examples
matrix = rotation_from_angles([np.pi/2, 0, 0], 'XYX')
matrix.dot([0, 1, 0])
# array([0., 0., 1.])

matrix = rotation_around_axis([1, 0, 0], np.pi/2)
matrix.dot([0, 1, 0])
# array([0., 0., 1.])

matrix = rotation_around_x(np.pi/2)
matrix.dot([0, 1, 0])
# array([0., 0., 1.])

# n-dimensional example
matrix = rotation_from_angle_and_plane(np.pi/2, (0, 1, 0, 0), (0, 0, 1, 0))
matrix.dot([0, 1, 0, 0])
# array([0., 0., 1., 0.])

# n-dimensional random matrix O(n), e.g. n=27
matrix = random_matrix(27)
