/**
* Multiplies each element in an input one-dimensional double-precision complex floating-point ndarray by a scalar constant and assigns the results to elements in a one-dimensional double-precision complex floating-point output ndarray.
*
* ## Notes
*
* - The function expects the following ndarrays:
*
* - a one-dimensional input ndarray.
* - a one-dimensional output ndarray.
* - a zero-dimensional ndarray containing the scalar constant to multiply.
*
* @private
* @param {ArrayLikeObject<Object>} arrays - array-like object containing ndarrays
* @returns {ndarray} output ndarray
*
* @example
* var Complex128Vector = require( '@stdlib/ndarray/vector/complex128' );
* var Complex128 = require( '@stdlib/complex/float64/ctor' );
* var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
*
* var x = new Complex128Vector( [ -2.0, 1.0, 3.0, -5.0 ] );
* var w = new Complex128Vector( 2 );
*
* var alpha = scalar2ndarray( new Complex128( 5.0, 0.0 ), {
* 'dtype': 'complex128'
* });
*
* var out = zwax( [ x, w, alpha ] );
* // returns <ndarray>[ <Complex128>[ -10.0, 5.0 ], <Complex128>[ 15.0, -25.0 ] ]
*
* var bool = ( out === w );
* // returns true
