# conj

Complex conjugate

## Syntax

``Zc = conj(Z)``

## Description

example

````Zc = conj(Z)` returns the complex conjugate of each element in `Z`.```

## Examples

collapse all

Find the complex conjugate of the complex number `Z`.

`Z = 2+3i`
```Z = 2.0000 + 3.0000i ```
`Zc = conj(Z)`
```Zc = 2.0000 - 3.0000i ```

Create a 2-by-2 matrix with complex elements.

`Z = [0-1i 2+1i; 4+2i 0-2i]`
```Z = 2×2 complex 0.0000 - 1.0000i 2.0000 + 1.0000i 4.0000 + 2.0000i 0.0000 - 2.0000i ```

Find the complex conjugate of each complex number in matrix `Z`.

`Zc = conj(Z)`
```Zc = 2×2 complex 0.0000 + 1.0000i 2.0000 - 1.0000i 4.0000 - 2.0000i 0.0000 + 2.0000i ```

## Input Arguments

collapse all

Input array, specified as a scalar, vector, matrix, or multidimensional array. `conj` operates element-wise when `Z` is nonscalar.

Data Types: `single` | `double` | `int8` | `int16` | `int32` | `int64` | `uint8` | `uint16` | `uint32` | `uint64` | `logical`
