I dont think that this program uses the gaussian function, am I in the right
wavelength?
from __future__ import division
import math
a=raw_input("What is the value of xmin?")
b=raw_input("What is the value of dx?")
c=raw_input("What is the value of nx?")
xmin=float(a)
dx=float(b)
nx=int(c)
n=int(c)
l=[]
for x in range(0.00,n):
print xmin+x*dx
def line(n):
s=''
i=raw_input("Please choose a scale for your plot")
n=int(i)
for j in range(0.00,n):
s= s+ "***" + "\n"
print s
return s
def gauss(x):
gaussa=math.pi(2)
gaussb=math.sqrt(gaussa)
gaussc=1/gaussb
gaussd=math.exp(-0.5*-2.00**2)
gausse= gaussc*gaussd
print gausse
