In this code, you are selecting all of the first dimension of the array using just the colon. NumPy and Python in general also use the colon for the slice syntax, but the order of the values is slightly different. In Python, the order is start : stop : step, whereas in MATLAB, it...

In the same spirit, the array can be sliced for operations: b=np.array([1,2,3])c=b+a[0, :]# call of __getitem__ However, one important distinction is that array slicing does not create views as flexible as NumPys. The following will not changeaas it would in Python. ...
