mrdivide, /
Right-matrix division
Description
Examples
Divide fi Matrix by a Constant
In this example, you use the forward slash (/) operator to perform right matrix division on a 3-by-3 magic square of fi
objects. Because the numerator input is a fi
object, the denominator input b
must be a scalar.
A = fi(magic(3))
A = 8 1 6 3 5 7 4 9 2 DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 16 FractionLength: 11
b = fi(3,1,12,8)
b = 3 DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 12 FractionLength: 8
X = A/b
X = 2.6250 0.3750 2.0000 1.0000 1.6250 2.3750 1.3750 3.0000 0.6250 DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 16 FractionLength: 3
Perform Matrix Division
You can perform right-matrix division when neither input is a fi
object. The matrix dimensions must be compatible for matrix division.
A = [2, 3, 1; 0, 8, 4; 1, 1, 0]
A = 3×3

Input Arguments
A
— Numerator
scalar | vector | matrix | multidimensional array
Numerator, specified as a scalar, vector, matrix, or multidimensional array. If one
or both of the inputs is a fi
object, then b
must be a scalar. When b
is a scalar, mrdivide
is equivalent to rdivide
.
Data Types: single
| double
| int8
| int16
| int32
| int64
| uint8
| uint16
| uint32
| uint64
| logical
| fi
Complex Number Support: Yes
b
— Denominator
scalar | vector | matrix | multidimensional array
Denominator, specified as a real scalar, vector, matrix, or multidimensional array.
If one or both of the inputs is a fi
object, then
b
must be a scalar. When b
is a scalar,
mrdivide
is equivalent to rdivide
.
If neither input is a fi
object, then the sizes of the input
matrices must be compatible for matrix division.
Data Types: single
| double
| int8
| int16

| int64
| uint8
| uint16
| uint32
| uint64

Output Arguments
X
— Quotient
scalar | vector | matrix | multidimensional array
Solution, returned as an array with the same dimensions as the numerator input
A
. When A
is complex, the real and imaginary
parts of A
are independently divided by b
.
