/**
* Calculates the dot product of two single-precision complex floating-point vectors.
*
* @param {integer} N - number of indexed elements
* @param {Complex64Array} x - first input array
* @param {integer} strideX - `x` stride length
* @param {NonNegativeInteger} offsetX - starting index for `x`
* @param {Complex64Array} y - second input array
* @param {integer} strideY - `y` stride length
* @param {NonNegativeInteger} offsetY - starting index for `y`
* @returns {Complex64} dot product
*
* @example
* var Complex64Array = require( '@stdlib/array/complex64' );
