[Scilab-users] quaternion

[Lamy Alain]

Multiplication, division, inverse...
CelestLab contains all these operations.  

There is a short description in the help page: 
CelestLab >> - Introduction - > Usage and conventions > Data types

For instance: 
You can create quaternions by using the functions CL_rot_defQuat, CL_rot_angles2Quat ...
q1 = ...
q2 = ...
then multiply the quaternions : 
q = q1 * q2 
...

Thanks for reply. But it seems CelestLab uses the quaternions specifically for coordinate transformation. I don't find even the multiplication of quaternions.

Any other suggestions?
