Applies a plane rotation.

@param {PositiveInteger} N - number of indexed elements
@param {Complex64Array} x - first input array
@param {integer} strideX - `x` stride length
@param {NonNegativeInteger} offsetX - starting `x` index
@param {Complex64Array} y - second input array
@param {integer} strideY - `y` stride length
@param {NonNegativeInteger} offsetY - starting `y` index
@param {number} c - cosine of the angle of rotation
@param {number} s - sine of the angle of rotation
@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, 7.0, 8.0 ] );
