Hi everybody.
Am new to Spyder (and Python in general), I just downloaded it on Mac OSX 
and installed from the DMG.
I have some trouble with the Code Analysis.

In my script editor, some functions like linspace, plot, savefig, etc. are 
marked with a warning sign, whose info box says somethings like:

Code Analysis
____________
undefined name 'linspace'

I have no idea if this is a regular error. I haven't seen any related posts.
Do I have to config something, or install something extra?

For example, such error appear on this sample code:

from scipy import special, optimize

f = lambda x: -special.jv(3, x)

sol = optimize.minimize(f, 1.0)

x = linspace(0, 10, 5000)

x

plot(x, special.jv(3, x), '-', sol.x, -sol.fun, 'o')

savefig('plot.png', dpi=96)


which runs without problems.


Thank you very much


Best regards


Edgar
