CL_rot_eul2quat

Description

• This function is deprecated.

  Replacement function: CL_rot_angles2quat

• Computes the quaternion that corresponds to the combination of 3 successive rotations of respective angles phi, theta, psi around axes number 1 (x-axis), 2 (y-axis), 3 (z-axis) respectively.

  

• Notes:

  - See Data types or CL_rot_defQuat for more details on quaternions.

Parameters

phi :

Rotation angle around the first (X) axis [rad] (1xN)

theta :

Rotation angle around the second (Y) axis [rad] (1xN)

psi :

Rotation angle around the third (Z) axis [rad] (1xN)

q :

Quaternion (dim N)

Examples

// Example 1 phi = 0.2; // radians theta = 0.3; psi = 0.4; q = CL_rot_eul2quat(phi,theta,psi) // Same computation with matrix: M = CL_rot_angles2matrix([1,2,3], [phi;theta;psi]); q = CL_rot_matrix2quat(M)
