Try return 2*ones(shape(x))
The problem is that you are returning a scalar
Use this to plot it:
plot([x], [f(x)])you need the square brackets.

Hi,
I am having trouble graphing constant functions in matplotlib (a simple
y = 2). Here is a simple test script I'm using:
from pylab import *
def f(x):
return 2
x = arange(1, 4)
plot(x, f(x))
show()
When I run it, I get this error:
Traceback (most recent call last):
File "test",
