        ```
        
        ### Example:
        ```python
        import numpy as np
        from ismember import ismember
        
        # Example with lists
        a_vec  = [1,2,3,None]
        b_vec  = [4,1,2]
        [I,idx] = ismember(a_vec,b_vec)
        np.array(a_vec)[I]
        np.array(b_vec)[idx]
        
        # Example with DataFrames
        a_vec = pd.DataFrame(['aap','None','mies','aap','boom','mies',None,'mies','mies','pies',None])
        b_vec = pd.DataFrame([None,'mies','mies','pies',None])
        I, idx = ismember(a_vec,b_vec)
        a_vec.values[I]
        b_vec.values[idx]
        
        a_vec = np.array([1,2,3,None])
        b_vec = np.array([1,2,4])
        I, idx = ismember(a_vec,b_vec)
        a_vec[I]
        b_vec[idx]
        
        # Example with Numpy array
        a_vec = np.array(['boom','aap','mies','aap'])
        b_vec = np.array(['aap','boom','aap'])
        I, idx = ismember(a_vec,b_vec)
        a_vec[I]
        b_vec[idx]
        
        # Example with matrices
        # Create two random matrices
        a_vec = np.random.randint(0,10,(5,8))
        b_vec = np.random.randint(0,10,(5,10))
        
        # Row-wise comparison
        Iloc, idx = ismember(a_vec, b_vec, 'elementwise')
        # Print results for the first row:
        a_vec[i,Iloc[0]]==b_vec[i,idx[0]]
        
        # Row wise comparison
        a_vec = np.array(((1, 2, 3), (4, 5, 6), (7, 8, 9), (10, 11, 12)))
        b_vec = np.array(((4, 5, 6), (7, 8, 0)))
        Iloc, idx = ismember(a_vec, b_vec, 'rows')
        
        ```
