Interchanges two complex single-precision floating-point vectors.

@param {PositiveInteger} N - number of indexed elements
@param {Complex64Array} x - first input array
@param {integer} strideX - `x` stride length
@param {Complex64Array} y - second input array
@param {integer} strideY - `y` stride length
@returns {Complex64Array} `y`

@example
var Complex64Array = require( '@stdlib/array/complex64' );

var x = new Complex64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
var y = new Complex64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );

cswap( x.length, x, 1, y, 1 );
// x => <Complex64Array>[ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ]
// y => <Complex64Array>[ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ]
