Divide a Quaternion Array by a Real Scalar
Create a 2-by-1 quaternion array, and divide it element-by-element by a real scalar.
A = quaternion([1:4;5:8])
A = 2x1 quaternion array
1 + 2i + 3j + 4k
5 + 6i + 7j + 8k
B = 2; C = A.\B
C = 2x1 quaternion array

0.057471 - 0.068966i - 0.08046j - 0.091954k
Divide a Quaternion Array by Another Quaternion Array
Create a 2-by-2 quaternion array, and divide it element-by-element by another 2-by-2 quaternion array.
q1 = quaternion([1:4;2:5;4:7;5:8]); A = reshape(q1,2,2)
A = 2x2 quaternion array
1 + 2i + 3j + 4k 4 + 5i + 6j + 7k
2 + 3i + 4j + 5k 5 + 6i + 7j + 8k
q2 = quaternion(magic(4)); B = reshape(q2,2,2)
B = 2x2 quaternion array
16 + 2i + 3j + 13k 9 + 7i + 6j + 12k
5 + 11i + 10j + 8k 4 + 14i + 15j + 1k
C = A.\B
C = 2x2 quaternion array

Input Arguments
A
— Divisor
quaternion
object | array of quaternion
objects | real scalar | array of real numbers
Divisor, specified as a quaternion
object, an
array of quaternion
objects of any dimensionality, a real scalar, or an
array of real numbers of any dimensionality. Numeric values must be of data type
single
or double
.
A
and B
must have compatible sizes. In the
simplest cases, they can be the same size or one can be a scalar. Two inputs have
compatible sizes if, for every dimension, the dimension sizes of the inputs are the same
or one of the dimensions is 1.
B
— Dividend
quaternion
object | array of quaternion
objects | real scalar | array of real numbers
Dividend, specified as a quaternion
object, an
array of quaternion
objects of any dimensionality, a real scalar, or an
array of real numbers of any dimensionality. Numeric values must be of data type
single
or double
.
A
and B
must have compatible sizes. In the

Output Arguments
C
— Result
quaternion
object | array of quaternion
objects
Result of quaternion division, returned as a quaternion
object or
an array of quaternion
objects.
