Free space loss 3D Plot - scimi - Sep-25-2020
Hello everyone
I have the function:
#free space loss calculation
def fspl(d, f):
x = 4*math.pi
ls = 3*10**8
result = 20*math.log10(d)+20*math.log10(f)+20*math.log10(x/ls)
return resultand two of the axis:f = np.linspace(0,10000)
d = np.linspace(0,1000000)
How can I plot this into a 3D Surface with the axis frequency (y), distance (x) and free space loss (z)?
Thanks a lot for your help already in advance!
RE: Free space loss 3D Plot - scimi - Sep-25-2020
I proceeded a bit and got the following code but there is still an error 'only size-1 arrays can be converted to Python scalars'. What's wrong with my code?
import math
from mpl_toolkits import mplot3d
import numpy as np
import matplotlib.pyplot as plt
ax = plt.axes(projection='3d')
def function(d, f):
x = 4*math.pi
ls = 3*10**8
test = 20*math.log10(d)+20*math.log10(f)+20*math.log10(x/ls)
return test
x = np.linspace(0,10, 100)
y = np.linspace(0,10, 100)
X,Y = np.meshgrid(x,y)
Z = function(X,Y)
ax.plot_surface(X,Y,Z)
plt.show()
