/**
* Computes the sum of all elements in a one-dimensional double-precision complex floating-point ndarray.

* ## Notes
*
* -   The function expects the following ndarrays:

*     -   a one-dimensional input ndarray.
*
* @private
* @param {ArrayLikeObject<Object>} arrays - array-like object containing ndarrays
* @returns {Complex128} sum
*
* @example
* var Complex128Vector = require( '@stdlib/ndarray/vector/complex128' );
*
* var x = new Complex128Vector( [ 1.0, 3.0, 4.0, 2.0 ] );
*
* var v = zsum( [ x ] );
* // returns <Complex128>[ 5.0, 5.0 ]
