How to plot curves with matplotlib

Question

I am trying to plot the Sigmoid Function, is that possible?

Answer 1

You can use numpy and matplotlib for that.

For this example:

import numpy as np
import matplotlib.plot as plt

def sigmoid(x):
return 1./(1+np.exp(-x))

x = np.linspace(-5,5,50) #prints 50 points from -5 to 5 in equal distance

y = sigmoid(x)

plt.plot(x,y)
plt.show()

for more Information consult the documentation of numpy and matplotplib (google)
