Re: [Numpy-discussion] Using normal()

In the application's function I now have:

from numpy import *

x = nx.arange(0, 100, 0.1) y = nx.normal(center,width) # passed to the function when called

and I then pass x,y to PyX for plotting. But python responds with:

y = nx.normal(center,width) AttributeError: 'module' object has no attribute 'normal'

It's random.normal(loc, scale). But that will give you random x values drawn from the normal distribution, not y values at your x. So you'll have to code your own normal, which will probably look something like norm = 1 / (scale * sqrt(2 * pi)) y = norm * exp(-power((x - loc), 2) / (2 * scale**2))
