* Multiplies a double-precision floating-point strided array `x` by a constant and adds the result to a double-precision floating-point strided array `y` multiplied by a constant using alternative indexing semantics.
*
* @param {PositiveInteger} N - number of indexed elements
* @param {number} alpha - first scalar constant
* @param {Float64Array} x - input array
* @param {integer} strideX - `x` stride length
* @param {NonNegativeInteger} offsetX - starting `x` index
* @param {number} beta - second scalar constant
* @param {Float64Array} y - output array
* @param {integer} strideY - `y` stride length
* @param {NonNegativeInteger} offsetY - starting `y` index
* @returns {Float64Array} output array
*
* @example
* var Float64Array = require( '@stdlib/array/float64' );
*
* var x = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0 ] );
* var y = new Float64Array( [ 2.0, 3.0, 4.0, 5.0, 6.0 ] );
*
* daxpby( x.length, 5.0, x, 1, 0, 2.0, y, 1, 0 );
* // y => <Float64Array>[ 9.0, 16.0, 23.0, 30.0, 37.0 ]
