+* Computes the dot product of two double-precision complex floating-point vectors.
+*
+* @param {integer} N - number of indexed elements
+* @param {Complex128Array} x - first input array
+* @param {integer} strideX - `x` stride length
+* @param {NonNegativeInteger} offsetX - starting index for `x`
+* @param {Complex128Array} y - second input array
+* @param {integer} strideY - `y` stride length
+* @param {NonNegativeInteger} offsetY - starting index for `y`
+* @returns {Complex128Array} dot product array
+*
+* @example
+* var Complex128Array = require( '@stdlib/array/complex128' );
+*
+* var x = new Complex128Array( [ 4.0, 2.0, -3.0, 5.0, -1.0, 7.0 ] );
+* var y = new Complex128Array( [ 2.0, 6.0, -1.0, -4.0, 8.0, 9.0 ] );
+*
+* var z = zdotu( 3, x, 1, 0, y, 1, 0 );
+* // returns <Complex128Array>[ -52.0, 82.0 ]
