find vector part of a quaternion in octave

Question

I am working in octave. I have a quaternion vector q . Let say it's scalar component is q1 and the vector components are q2,q3,q4 . I need the values of q1,q2,q3,q4 seperately using octave. For example,

if q = 1 + 2i + 3j + 4k
then q1 = 1 , q2 = 2 , q3 = 3 , q4 = 4 ;

I have googled but have not found any function to implement this in octave. Thanks in advance for your help.

Answer 1

I found the answer on the sourceforge documentation page

octave:32> a=quaternion(1,2,3,4);
octave:33> a

a = 1 + 2i + 3j + 4k

octave:34> a.w

ans =  1

octave:35> a.x

ans =  2

octave:36> a.y

ans =  3

octave:37> a.z

ans =  4
