问题描述
我正在使用n维数组，我想一种反转编号维的方法.所以，而不是
I'm working with an n-dimensional array, and I'd like a way to reverse a numbered dimension. So rather than
rev = a[:,:,::-1]
我想写
rev = a.reverse(dimension=2)
或类似的东西.我似乎找不到不依赖以前语法的示例.
or something similar. I can't seem to find examples that don't rely on the former syntax.
推荐答案
对于以后遇到此问题的任何人:
For anyone coming across this in the future:
Numpy 1.12+具有功能 np.flip(array, dimension) ，完全按照要求执行.更好的是，它返回的是数据视图而不是副本，因此它发生的时间是恒定的.
Numpy 1.12+ has the function np.flip(array, dimension), which does exactly as requested. Even better, it returns a view of the data rather than a copy, and so it happens in constant time.
