NumPy有三个看起来可以用于相同事情的不同函数 --- 除了numpy.maximum只能针对每个元素使用,而numpy.max和numpy.amax可以用于特定轴或所有元素。为什么不止有numpy.max?这是否涉及到性能上的微妙差别? (类似地,对于min vs. amin vs. minimum) - DilithiumMatrix4个回答254 np.max 是np.amax 的别名。该函数仅...

numpy-minmax: a fast function for finding the minimum and maximum value in a NumPy array NumPy lacked an optimized minmax function, so we wrote our own. At Nomono, we use it for audio processing, but it can be applied any kind of float32 ndarray. Written in C and takes advantage of ...
numpy.maximum now raises a RuntimeWarning when encountering a NaN, but the documentation says it propagates NaNs and even goes to the trouble of saying exactly how they are propagated, which makes it seem like it shouldn't give a warning. Reproducing code example: In [1]: import numpy as...
xmax2 = numpy.ma.maximum.reduce(vd.subSlice(),axis=0)ifnotMV2.allclose(xmax, xmax2): markError('maximum.reduce')## minimum(a, b=None)## returns minimum element of a single array, or elementwiseminval = MV2.minimum(xouter)
While comparing, one of the elements of two arrays is a NaN, then that element is returned as NaN. If both elements of two arrays are NaNs then the first element is returned. Use the minimum() function to get the minimum values of NumPy array....
