Hi,
Look in IPython/Shell.py to see how pylab option is being evaluated. And
similarly in matplotlib/lib/matplotlib/pylab.py
Also in your ipythonrc file you can unset pylab_import_all option to have a
clearer namespace (i.e. the contents of pylab.py will not be explicitly
loaded.)
And yes those are the same NumPy arrays. You can always check this by "type"
builtin.
