array : [array_like]Input array or object whose elements, we need to test for infinity out : [ndarray, optional]Output array placed with result. Its type is preserved and it must be of the right shape to hold the output.
boolean array containing the result
Code 1 :
Finite : True Finite : True Finite : False Finite : False Finite : False
Code 2 :
[[ 0 1 2 3] [ 4 5 6 7] [ 8 9 10 11] [12 13 14 15] [16 17 18 19]] Is Finite : [[ True True True True] [ True True True True] [ True True True True] [ True True True True] [ True True True True]] Is Finite : [[ True] [False]]
