Logarithmic Values of Quaternion Array
Create a 3-by-1 quaternion array A.
A = quaternion(randn(3,4))
A = 3x1 quaternion array
0.53767 + 0.86217i - 0.43359j + 2.7694k
1.8339 + 0.31877i + 0.34262j - 1.3499k
-2.2588 - 1.3077i + 3.5784j + 3.0349k
Compute the logarithmic values of A.
B = log(A)
B = 3x1 quaternion array
1.0925 + 0.40848i - 0.20543j + 1.3121k
0.8436 + 0.14767i + 0.15872j - 0.62533k
1.6807 - 0.53829i + 1.473j + 1.2493k
Input Arguments
