parts

Extract quaternion parts

Description

example

[a,b,c,d] = parts(quat) returns the parts of the quaternion array as arrays, each the same size as quat.

Examples

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 object
     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

qC = 2×1

Quaternion, specified as a quaternion or array of quaternions.

Data Types: quaternion

Output Arguments

collapse all

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

Data Types: single | double
