numpy.linspace(start, stop, num=50, endpoint=True, retstep=False, dtype=None, axis=0)
-> start : [optional] start of interval range. By default start = 0
-> stop : end of interval range
-> num : [int, optional] No. of samples to generate
-> restep : If True, return (samples, step). By default restep = False
-> dtype : type of output array
