Quaternion subtraction
Syntax
Description
Examples
Subtract a Quaternion from a Quaternion
Quaternion subtraction is defined as the subtraction of the corresponding parts of each quaternion. Create two quaternions and perform subtraction.
Q1 = quaternion([1,0,-2,7]); Q2 = quaternion([1,2,3,4]); Q1minusQ2 = Q1 - Q2
Q1minusQ2 = quaternion
0 - 2i - 5j + 3k
Subtract a Real Number from a Quaternion
Addition and subtraction of real numbers is defined for quaternions as acting on the real part of the quaternion. Create a quaternion and then subtract 1 from the real part.
Q = quaternion([1,1,1,1])
Q = quaternion
1 + 1i + 1j + 1k
Qminus1 = Q - 1
Qminus1 = quaternion
0 + 1i + 1j + 1k
Input Arguments
A
— Input
quaternion
object | array of quaternion
objects | real scalar | array of real numbers
Input, 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
— Input
quaternion
object | array of quaternion
objects | real scalar | array of real numbers
Input, 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
.

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