/**
* Returns the index of the first element in a double-precision complex floating-point strided array which is less than a corresponding element in another double-precision complex floating-point strided array.
*
* ## Notes
*
* - When comparing elements, the function checks whether both the real and imaginary components of an element in `x` are less than the corresponding real and imaginary components of an element in `y` using the less-than operator `<`. As a consequence, comparisons involving `NaN` always evaluate to `false`.
* - If the function is unable to find an element in `x` which is less than a corresponding element in `y`, the function returns `-1`.
*
* @param {PositiveInteger} N - number of indexed elements
* @param {Complex128Array} x - first input array
* @param {integer} strideX - stride length for `x`
* @param {Complex128Array} y - second input array
* @param {integer} strideY - stride length for `y`
* @returns {integer} index
*
* @example
* var Complex128Array = require( '@stdlib/array/complex128' );
*
* var x = new Complex128Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );
* var y = new Complex128Array( [ 0.0, 0.0, 0.0, 0.0, 1.0, 1.0, 0.0, 0.0 ] );
*
* var idx = zfirstIndexLessThan( x.length, x, 1, y, 1 );
* // returns 2
