[Python] numpy.logspace

numpy.logspace(start, stop, num=50, endpoint=True, base=10.0, dtype=None)

 

starting value  :=  base**start

stopping value  :=  base**stop

 

base = 10.0  :=  the base of the log space

 

Ex:

Input:

np.logspace(1,2,10, base = 10.0)

　　

Output:

array([  10.        ,   12.91549665,   16.68100537,   21.5443469 ,
         27.82559402,   35.93813664,   46.41588834,   59.94842503,
         77.42636827,  100.        ])
