1, 1], [2, 3]]): Creates a 2x2 NumPy array with elements 1, 1, 2, and 3. print(np.unique(x)): The np.unique function works with multi-dimensional arrays as well. It flattens the input array and then returns the
Find the unique elements of an array. Returns the sorted unique elements of an array. There are three optional outputs in addition to the unique elements: the indices of the input array that give the unique values, the indices of the unique array that reconstruct the input array, and the n...
