# ?lacgv

Conjugates a complex vector.

## Syntax

call clacgv( n, x, incx )

call zlacgv( n, x, incx )

## Description

This routine conjugates a complex vector x of length n and increment incx (see “Vector Arguments in BLAS” in Appendix B).

## Input Parameters

n

  INTEGER. The length of the vector x (`n ≥ 0`).

x

  COMPLEX for clacgv

  COMPLEX*16 for zlacgv.

  Array, dimension `(1+(n-1)* |incx|)`.

  Contains the vector of length n to be conjugated.

incx

  INTEGER. The spacing between successive elements of x.

## Output Parameters

x

  On exit, overwritten with conjg(x).
