* Fills a strided array with pseudorandom integers on the interval `[1, 2147483646]`.

* @param {NonNegativeInteger} N - number of indexed elements
* @param {Collection} out - output array
* @param {integer} so - `out` stride length
* @param {Options} [options] - function options
* @param {PRNGSeedMINSTD} [options.seed] - pseudorandom number generator seed
* @param {PRNGStateMINSTD} [options.state] - pseudorandom number generator state
* @param {boolean} [options.copy=true] - boolean indicating whether to copy a provided pseudorandom number generator state
* @throws {Error} must provide valid options
* @throws {Error} must provide a valid state
* @returns {Collection} output array
