And the same for tau close to 0.

Detect discretization issues in ss2sim

1

Sometimes `ss2sim` (via `LinearSystem`) will destabilize `sys` when discretizing it with the given `dt`. This occurs for larger order delays that are not properly balanced / normalized. A workaround is...

Currently this is not done as a hack in order to prevent `num` and `den` from being frozen. But this means that: ``` nengolib.signal.s._params ``` will raise an exception, because:...

Would be good to get this unit test passing: ```def test_zerodim_system(): sys = LinearSystem(1) ss_sys = LinearSystem(sys.ss) assert len(ss_sys) == 0 ``` but the dimension can be 0 or 1...

And document limitations in related functions / methods.

Currently only checks that `isinstance(pre, nengo.Ensemble)`.

[DOC] Levinson–Durbin recursion for computing Pade approximants

This may be useful for analysis. A work-in-progress: ``` import numpy as np from scipy.misc import factorial, pade # Taylor series c = 1. / factorial(np.arange(10)) # Array representing the...
