Convert a quaternion representation to parts using the parts function.

Create a two-element column vector of quaternions by specifying the parts.

quat = quaternion([1:4;5:8])
quat = 2×1 quaternion array
     1 + 2i + 3j + 4k
     5 + 6i + 7j + 8k

Recover the parts from the quaternion matrix using the parts function. The parts are returned as separate output arguments, each the same size as the input 2-by-1 column vector of quaternions.

[qA,qB,qC,qD] = parts(quat)
qA = 2×1

     1

qB = 2×1

     6


qC = 2×1

Quaternion, specified as a quaternion object or an array of quaternion objects of any dimensionality.

Output Arguments

Quaternion parts, returned as four comma-separated numeric arrays: a, b, c, and d. Each part is the same size as quat.
