NumPy: Checking if an array contains another subarray (3 examples)
It returns True if the subarray is found, indicating the presence of the subarray within the larger array. Example 2: Using Strides for Efficient Searching. Next, we’ll leverage NumPy’s powerful handling of array strides to search for the subarray in a more efficient manner. This method is particularly useful for large datasets.
