I'm trying to draw plots in Python with Scipy module. According to http://docs.scipy.org/doc/scipy/reference/special.html I wrote code with scipy.special.spherical_jn(n,x,0)
:
import matplotlib.pyplot as plt
import numpy as np
import scipy.special as sp
from matplotlib import rcParams
rcParams.update({'figure.autolayout': True})
def odrazTE(a,o,d):
temp1 = sp.spherical_jn[1,a,0]
temp2 = 1
return abs(temp1/temp2)**2
t = np.arange(0.001, 2, 0.001)
plt.plot(t,odrazTE(t,t,1),label='TE1')
plt.show()
While I'm compiling the program, all I get is this error:
Traceback (most recent call last):
File "standing-sphere.py", line 33, in <module>
plt.plot(t,odrazTE(t,t,1),label='TE1')
File "standing-sphere.py", line 15, in odrazTE
temp1 = sp.spherical_jn[1,a,0]
AttributeError: 'module' object has no attribute 'spherical_jn'
There is way how to do it with regular Bessel function and relationship between Bessel and spherical Bessel function, but I don't like this solution because of derivative of sph.bess. function that I need too.
Is there any chance I have set something wrongly and it can be fixed to scipy.special.spherical_jn work?
