function csscal( N, alpha, x, strideX ) {
	return ndarray( N, alpha, x, strideX, stride2offset( N, strideX ) );
}
Scales a single-precision complex floating-point vector by a single-precision floating-point constant.

@param {PositiveInteger} N - number of indexed elements
@param {number} alpha - constant
@param {Complex64Array} x - input array
@param {integer} strideX - `x` stride length
@returns {Complex64Array} input array

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

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

csscal( 3, 2.0, x, 1 );
// x => <Complex64Array>[ 2.0, 4.0, 6.0, 8.0, 10.0, 12.0 ]
