gaussian plot

20160731

Plot a couple of Gaussians

import numpy as np
from math import pi
from math import sqrt
import matplotlib.pyplot as plt


def gaussian(x, mu, sig):
    return 1./(sqrt(2.*pi)*sig)*np.exp(-np.power((x - mu)/sig, 2.)/2)

xv= map(lambda x: x/10.0, range(0,120,1))

mu= [ 2.0, 7.0, 9.0 ]
sig=[ 0.45, 0.70, 0.3 ] 

for g in range(len(mu)):
    m=mu[g]
    s=sig[g]
    yv=map( lambda x: gaussian(x,m,s), xv ) 
    plt.plot(xv,yv)

plt.show()
