Numpy minimum in (row, column) format
32,580
Solution 1
Use unravel_index
:
numpy.unravel_index(A.argmin(), A.shape)
Solution 2
[Corrected typo]
Another simple solution is
ri, ci = A.argmin()//A.shape[1], A.argmin()%A.shape[1]
As numpy.argmin returns the index reading in row-major order
Yes, you are right, it was a typo, which worked for square matrix

How can I know the (row, column) index of the minimum of a numpy array/matrix?
For example, if
A = array([[1, 2], [3, 0]])
, I want to get(1, 1)
Thanks!
