## Detailed Description

## Function Documentation

### subroutine clacgv (integer n, complex, dimension( \* ) x, integer incx)

**CLACGV** conjugates a complex vector.

**Purpose:**

```
!>
!> CLACGV conjugates a complex vector of length N.
!>
```

**Parameters**

*N*

```
!>          N is INTEGER
!>          The length of the vector X.  N >= 0.
!>
```

*X*

```
!>          X is COMPLEX array, dimension
!>                         (1+(N-1)*abs(INCX))
!>          On entry, the vector of length N to be conjugated.
!>          On exit, X is overwritten with conjg(X).
!>
```

*INCX*

```
!>          INCX is INTEGER
