[Chennaipy] Query on numpy.logspace() in Python

[rajeshkumar p]

Hi,

The below snippet will add few info:

>>> import numpy as np
>>> np.logspace(2, 4, num=1, base=10)
array([100.])

# Our result is 10**2

>>> np.logspace(2, 4, num=2, base=10)
array([  100., 10000.])

# Our result is 10**2, 10**3


>>> np.logspace(2, 4, num=3, base=10)
array([  100.,  1000., 10000.])

# Our result is 10**2, 10**3, 10**4


>>> np.logspace(2, 4, num=4, base=10)
array([  100.        ,   464.15888336,  2154.43469003, 10000.        ])



>>> np.linspace(2, 4, num=4)
array([2.        , 2.66666667, 3.33333333, 4.        ])
>>> np.power(10, np.linspace(2, 4, num=4))
array([  100.        ,   464.15888336,  2154.43469003, 10000.        ])


### Observation:
### np.power(10, np.linspace(2, 4, num=4)) is the same as np.logspace(2, 4,
num=4, base=10).

Hope this helps.

regards,
Rajeshkumar P
