max(axis=1)?
Hi Neal,
I should have been more precise in stating the problem. Getting the values in the array for which I'm looking at the maxima is only one step in a more complex piece of code for which I need the indexes along the second axis of the array. I would like to avoid to have to iterate the array more than once.
Thank you!
Cheers, Dan

Hello, this is a very basic question, but I cannot find a satisfying answer. Assume a is a 2D array and that I get the index of the maximum value along the second dimension: i = a.argmax(axis=1) Is there a better way to get the value of the maximum array entries along the second axis other than: v = a[np.arange(len(a)), i] ?? Thank you.
