提问by user1681664
I have 2 arrays.
我有 2 个数组。
a1 = [1,2,4]
a2 = [3,4,5]
how would I find the correlation between these 2 arrays using python.
我将如何使用 python 找到这两个数组之间的相关性。
In matlab, you would do:
在 matlab 中,你会这样做:
corr(a1,a2)
How to do this in python?

You need numpy.corrcoef:
你需要numpy.corrcoef:
In [8]:
np.corrcoef(a1,a2)
Out[8]:
array([[ 1. , 0.98198051],
[ 0.98198051, 1. ]])
