    FIX: signal.bode: don't crash on systems with a pole at 0

    bjornfor authored
    A system with max or min poles at 0 will cause bode() to crash when
    trying to determine a reasonable frequency range for the system. Fix
    that.

    Add abs() to signal.generalized_gaussian.
    
    So it works for values like p = 0.5 or 1.2 (which currently produce NaNs or asymmetrical windows).
    
    Clearly a bug now.

    ENH: ltisys: new bode() function

    bjornfor authored
    bode() calculates magnitude and phase data of a continuous-time system.
    
    Example:
      $ ipython --pylab
      >>> from scipy.signal import *
      >>> s1 = lti([1], [1, 1])
      >>> w, mag, phase = s1.bode()
      >>> semilogx(w, mag)    # bode magnitude plot
      >>> figure()
      >>> semilogx(w, phase)  # bode phase plot

    TST: signal: regression test for instantiation of lti class.

    Also expand its docstring.

    ENH: ltisys: make lti zpk initialization work with plain lists

    bjornfor authored rgommers committed
    lti objects can be created from a 3-tuple of zero-pole-gain (zpk)
    values. However, the current code only accepts numpy.array arguments,
    not plain lists.
    
    This is OK:
      >>> s = lti(array([]), array([-1]), 1)
    
    This is not:
      >>> s = lti([], [-1], 1)
      [...]
      AttributeError: 'list' object has no attribute 'shape'
    
    Using plain Python lists is intuitive and user friendly, so make that
    work as well.

    BUG: Fix Python 3 test failures.

    charris authored rgommers committed
    Some of these are due to deprecated test functions self.assertEquals,
    self.assert_, and some are due to the reinterpretion of '/'. Probably all
    test modules should have
    
    from __future__ import division
    
    at the top.
    
    Edit: reviewed at PR-163.
