## Usage
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var conj = require( '@stdlib/complex/conj' );
|
||
|
|
```
|
||
|
|
|
||
|
|
#### conj( z )
|
||
|
|
|
||
|
|
Returns the [complex conjugate][complex-conjugate] of a `complex` number.
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var Complex128 = require( '@stdlib/complex/float64' );
|
||
|
|
|
||
|
|
var z = new Complex128( 5.0, 3.0 );
|
||
|
|
var str = z.toString();
|
||
|
|
// returns '5 + 3i'
|
||
|
|
|
||
|
|
var v = conj( z );
|
||
|
|
str = v.toString();
|
||
|
|
// returns '5 - 3i'
|
||
|
|
```
