quat2axang
Convert quaternion to axis-angle rotation
Syntax
Description
Examples
Convert Quaternion to Axis-Angle Rotation
Input Arguments
quat
— Unit quaternion
n-by-4 matrix | n-element vector of quaternion
objects
Unit quaternion, specified as an n-by-4 matrix or n-element vector of
quaternion
objects containing n
quaternions. If the input is a matrix, each row is a quaternion vector of
the form q = [w
x
y
z], with w as the scalar
number.
Example: [0.7071 0.7071 0 0]
Output Arguments
axang
— Rotation given in axis-angle form
n-by-4 matrix
Rotation given in axis-angle form, returned as an n-by-4 matrix of n axis-angle rotations. The first three elements of every row specify the rotation axis, and the last element defines the rotation angle (in radians).
Example: [1 0 0 pi/2]
