本文简要介绍 python 语言中 numpy.ma.MaskedArray.sort 的用法。 用法: ma.MaskedArray.sort(axis=- 1, kind=None, order=None, endwith=True, fill_value=None)对数组进行就地排序参数: a: array_like 要排序的数组。 axis: 整数,可选 要排序的轴。如果为 None,则数组在排序前被展平。默认值为 -1,...
numpy.sort(a[, axis=-1, kind='quicksort', order=None]) Return a sorted copy of an array. axis:排序沿数组的(轴)方向,0表示按列,1表示按行,None表示展开来排序,默认为-1,表示沿最后的轴排序。 kind:排序的算法,提供了快排'quicksort'、混排'mergesort'、堆排'heapsort', 默认为‘quicksort'。
本文簡要介紹 python 語言中 numpy.recarray.sort 的用法。 用法: recarray.sort(axis=- 1, kind=None, order=None)就地對數組進行排序。有關完整文檔,請參閱 numpy.sort 。參數: axis: 整數,可選 要排序的軸。默認為 -1,表示沿最後一個軸排序。 kind: {‘quicksort’, ‘mergesort’, ‘heapsort’,...
