So, we call the sorted function, and pass the result a y.unique.

因此，我们调用 sorted 函数，并将结果传递给 y.unique。

And I loved this for one specific reason-- the sort function.

我之所以喜欢这个，是因为一个特定的原因——排序功能。

For example, pretty much every programming language comes with a built-in sort function, where you just pass in your array, and it comes back sorted.

例如，几乎每种编程语言都带有一个内置的排序函数，您只需传入数组，它就会排序返回。

Importantly, the more accurate the sorting function in MRFs, the higher quality the reprocessed material at the end, which is beneficial for companies looking to buy up that recyclate.

重要的是，MRF 中的分类功能越准确， 最终再加工材料的质量就越高， 这有利于希望购买回收材料的公司。
