Convert Quaternion Array to Compact Representation of Parts
Create a scalar quaternion with random parts. Convert the parts to a 1-by-4 vector using compact
.
randomParts = randn(1,4)
randomParts = 1×4
0.5377 1.8339 -2.2588 0.8622
quat = quaternion(randomParts)
quat = quaternion
0.53767 + 1.8339i - 2.2588j + 0.86217k
quatParts = compact(quat)
quatParts = 1×4
0.5377 1.8339 -2.2588 0.8622
Create a 2-by-2 array of quaternions, then convert the representation to a matrix of quaternion parts. The output rows correspond to the linear indices of the quaternion array.
quatArray = [quaternion([1:4;5:8]),quaternion([9:12;13:16])]
quatArray = 2x2 quaternion array
1 + 2i + 3j + 4k 9 + 10i + 11j + 12k
5 + 6i + 7j + 8k 13 + 14i + 15j + 16k
quatArrayParts = compact(quatArray)
quatArrayParts = 4×4
