How to use the NumPy linspace function
The NumPy linspace function (sometimes called np.linspace) is a tool in Python for creating numeric sequences. It's somewhat similar to the NumPy arange function, in that it creates sequences of evenly spaced numbers structured as a NumPy array. There are some...
