# zlacgv(3lapack)

conjugates a complex vector of length N

## NAME

ZLACGV - conjugates a complex vector of length N

## SYNOPSIS

- SUBROUTINE ZLACGV(

  N, X, INCX )

- INTEGER

  INCX, N

- COMPLEX\*16

  X( \* )

## PURPOSE

ZLACGV conjugates a complex vector of length N.

## ARGUMENTS

- N (input) INTEGER

  The length of the vector X.  N \>= 0.

- X (input/output) COMPLEX\*16 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 (input) INTEGER

  The spacing between successive elements of X.
