function zlacgv( N, zx, strideZX ) {
	return ndarray( N, zx, strideZX, stride2offset( N, strideZX ) );
}
Conjugates each element in a double-precision complex floating-point vector.

@param {PositiveInteger} N - number of indexed elements
@param {Complex128Array} zx - input array
@param {integer} strideZX - `zx` stride length
@returns {Complex128Array} input array

@example
var Complex128Array = require( '@stdlib/array/complex128' );
var real = require( '@stdlib/complex/float64/real' );
var imag = require( '@stdlib/complex/float64/imag' );

var zx = new Complex128Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );

zlacgv( 3, zx, 1 );

var z = zx.get( 0 );
// returns <Complex128>

var re = real( z );
// returns 1.0

var im = imag( z );
// returns -2.0
