* Performs an in-place copy of elements within a double-precision floating-point array.

* @param {PositiveInteger} N - number of indexed elements
* @param {integer} target - target index
* @param {Float64Array} x - input array
* @param {integer} strideX - stride length
* @param {NonNegativeInteger} offsetX - starting index
